Java string to string with quotes

How to add quotation marks within string Java? [SOLVED]

Quotation marks are a commonly used character in programming, especially when it comes to strings. In Java, there are two types of quotation marks that can be used to represent a string: single quotes (‘ ‘) and double quotes (» «). However, sometimes you may need to add quotation marks within a string. In this article, we’ll show you how to add quotation marks within a string in Java and provide some useful examples.

Introduction to Strings in Java

In Java, a string is a sequence of characters, often used to represent text or other data. Strings are objects in Java and are created using the String class. Here’s an example of how to create and use a string in Java:

This code creates a string called name and assigns the value «John Doe» to it. The println method is then used to print the message «Hello, John Doe» to the console.

In Java, strings are immutable, meaning that once a string is created, its value cannot be changed. If you need to modify a string, you must create a new string with the desired modification. For example:

This code creates two strings, greeting, and name, and concatenates them to create a new string, message. The resulting string is then printed to the console.

Adding Single Quotes within a Java String

Adding single quotes within a string in Java can be done by two different methods. First, we can use the escape character or using double quotation marks for the string.

In Java, the backslash tells Java that the following character is not a quote character but should be considered part of the string.

Here’s an example of how to add single quotes within a string in Java:

In this example, we create a string called singleQuoteString and assign the value «I’m a single quote string» to it. The backslash before the single quote character (‘) is used to escape the single quote, allowing it to be included within the string.

It’s important to note that in Java, you can use either single quotes or double quotes to represent a string, but you cannot mix and match within the same string. For example, if you want to include single quotes within a string represented by double quotes, you need to escape the single quotes using a backslash:

Another method is to put the single quotation marks inside the double quotation marks without using the escape character as shown below:

As you can see, this time we didn’t use the escape character but still were able to add the single quotation mark inside our string because we used double quotation marks for the string.

Adding Double Quotes within a Java String

Similar to the single quotation marks, double quotes within a string in Java can be done by escaping the double quote character using a backslash.

The backslash tells Java that the following character is not a quote character but should be considered part of the string.

Here’s an example of how to add double quotes within a string in Java:

I am a "double quote" string

In this example, we create a string called doubleQuoteString and assign the value «I am a «double quote» string» to it. The backslash before the double quote character («) is used to escape the double quote, allowing it to be included within the string.

Concatenating Strings to Include Quotation Marks

Concatenating strings to include quotation marks in Java can be done by using string concatenation operators (+) and escape sequences (\). In this way, you can combine multiple strings to create a single string that includes quotation marks.

Here’s an example of how to concatenate strings to include quotation marks in Java:

I am a string with "quotation marks" 

In this example, we create two strings, part 1 and part 2, and assign the values «I am a » and «string with «quotation marks»» to them, respectively. We then use the + operator to concatenate these two strings into a single string called combinedString. The backslash before the double quote character («) in the part 2 string is used to escape the double quote, allowing it to be included within the string.

Summary

In this article, we showed you how to add quotation marks within a string in Java. We covered three different methods for achieving this: escaping single and double quotes and using a backslash to escape quotation marks. No matter which method you choose, it’s important to understand the basics of how to include quotation marks within a string in Java.

  How to add double quotes around java object and string variable

  

  Learn how to add double quotes around java object and string variables by escaping characters in this two-minute guide. In every programming language single-quotes (‘ ’) and double-quotes (“ ”) are used for string variables initialization. Therefore, whenever you use these two symbols around a text, Java, javascript, c# and all other languages will treat such text as a string even if it’s a number surrounded with a single or double-quotes.

  So, if you have ever coded a project that you needed to add double quotes around a string, you can’t do it as you would in string variables initialization. Below is an example of what you might try to do.

  public class Main < public static void main(String args[]) < System.out.println("" Helloo world ""); >> /* OUTPUT: Exception in thread "main" java.lang.Error: Unresolved compilation problems: The left-hand side of an assignment must be a variable Syntax error on token "hellll", invalid AssignmentOperator at myjavaapp.Main.main(Main.java:8) */ 

  You can see that the Java virtual machine (JVM) couldn’t compile the above code. Why because it doesn’t understand what we are trying to print on the console. We have two double-quotes surrounded with the text we want to log to the console. The main problem is that the compiler can’t figure out what data-type such value should be compiled to.

  How do you add double quotes around java object and string variables easily?

  Let me show you an example of how to do it in few seconds…

  How do you add double quotes to a string variable in java?

  

  You can add double quotes to a string variable by using escape character symbol “\”. Using this symbol will notify the JVM to ignore the extra quotes around the text. All that you need to do is to add “\” in-front of the text and \”” at the end.

  Example, add double quotes to a String variable in java using escape characters.

  public class Main < public static void main(String args[]) < // Escape the needed double-quotes in the string System.out.println("\"Helloo world\""); >> /* OUTPUT: "Helloo world" */

  But what if you want to enclose or puts double-quotes around a certain part of string variable? For example, let say you want to display a story of 100 text length and part of it needs to be enclose in a quote, how can you achieve it? Java strings have a specific method called the replace() that you can use to manipulate your strings together with escape characters. Its easy, let me show you an example…

  public class Main < public static void main(String args[]) < // imagine we have this string and we want to surround the languages with quotes String me = "I love computer progamming languages like java and c#"; // use the replace() method to replace part of the string me = me.replace("java", "\"java\"").replace("c#", "\"c#\""); System.out.println(me); >> /* OUTPUT: I love computer progamming languages like "java" and "c#" */ 

  The string replace() will look through the string value and replace the matching text with the second arguments specified in the method. And since the value specified as a second argument does escape quotes, we are able to achieve the output we want.

  How do you concatenate double quotes in Java?

  You can concatenate double quotes in java by using the addition + operator. This operator is used for performing addition of numbers and concatenation of strings. We can use it to concatenate other quotes since we can escape sequence and join them together using the + operator. When I say concatenation, it simply means joining two or more values together.

  Double quotes concatenation example in Java

  public class Main < public static void main(String args[]) < // a string with quote: i know "Java" String languages = "i know \"Java\" "; // Concatenate double quotes to it System.out.println(languages + "and " + "\"c#\""); >> /* OUTPUT: i know "Java" and "c#" */

  How do you remove double quotes from a string in Java?

  You can use the replace() method to remove double quotes from a string variable.

  public class Main < public static void main(String args[]) < // a string with quote: i know "Java" String languages = "i know \"Java\""; languages = languages.replace("\"", ""); System.out.println(languages); >> /* OUTPUT: i know Java */

  How to split string with double quotes in java?

  How do you split a string with double quotes? The splite() method returns an array of certain values based on the condition, but in our case it should be a string. You can use this method to query a string variable and split the double quotes in it to an array.

  Example: Split string with double quotes in java

  public class Main < public static void main(String args[]) < String test = "Go to school at \"2022-10-04 03:30:00.0\""; // grab each text before the \ symbol String parts[] = test.split("\""); String part0 = parts[0]; String part1 = parts[1]; System.out.println(part0); System.out.println(part1); >> /* OUTPUT: Go to school at 2022-10-04 03:30:00.0 */
