How do you represent blank spaces in Java?

In Java, white space characters can be represented in the following way:

1. The Unicode value for a space character is 32. It can be represented as “\u0020”.
2. Java offers escape characters for using space character as well, such as “\s” to represent a space character.
3. In Java, you can directly use space characters in strings. For example, you can use ” ” to represent a space character.

The sample code is as follows:

String space1 = "\u0020";
String space2 = "\s";
String space3 = " ";

System.out.println(space1);
System.out.println(space2);
System.out.println(space3);

The output result is:

All of the above methods can be used to represent a space character, so you can choose the most appropriate way to represent a space character as needed.
