Java Escape Sequence

Java Escape Sequence

An important aspect of the Java programming language is the Escape Sequence which is followed by backslash. There are several things we can do with Escape Sequence. One thing to keep in mind, however, is that you cannot use uppercase letters here, but all letters will be lowercase. The use of Escape Sequence is discussed below such as: -

Escape Sequences Meaning
\b Backspace
\t Tab
\n New Line
\" Double Quote
\' Single Quote
\\ Backslash

How to use escape Sequence and these are discussed in detail such as: -

Use of backslash b :- \b

Escape Sequences Meaning
\b Backspace

\b :- This is used to delete a character. We know that the computer keyboard has a backslash button that allows us to delete any character. Similarly (\b) is used to delete a character in a Java program such as : -

File Name Main.java

Coped
package com.onlineashikhi;
public class Main {
public static void main(String[] args) {
// We Use Backslash \b Here
System.out.print( "Hello World\b" );
}
}

Output :-

 Hello Worl 

Use of backslash t :- \t

Escape Sequences Meaning
\t Tab

\t :- It is used to give a certain amount of distance. We know that there is a tab button on the computer keyboard by which a certain distance can be given. Similarly (\ t) is used to give a certain distance to something in a Java program. Such us: -

File Name Main.java

Coped
package com.onlineashikhi;
public class Main {
public static void main(String[] args) {
// We Use Backslash \t Here
System.out.println( "1 \t 2" );
System.out.println( "3 \t 4" );
System.out.println( "5 \t 6" );
}
}

Output :-

1     2
3     4
5     6

Use of backslash n :- \n

Escape Sequences Meaning
\n New Line

\n :- Java (\n) is used to create new lines. We know that new lines can be created in Java (println ()) by Mathhood. However, using (l n) does not require the use of (println ()) Mathhood. Such us: -

File Name Main.java

Coped
package com.onlineashikhi;
public class Main {
public static void main(String[] args) {
// We Use Backslash \n Here
System.out.print( ("This is first line\nThis is Second line\nThis is third line" );
}
}

Output :-

This is first line
This is Second line
This is third line

Use of backslash double quotation :- \"

Escape Sequences Meaning
\" Double Quote

\" : -If you want to give double quotation at a specific place in Java, you have to give backslash double quotation. The program used here I want to give double quotations on both sides. If you want you can give double quotation on one side. The use of (\ ") is given below as : -

File Name Main.java

Coped
package com.onlineashikhi;
public class Main {
public static void main(String[] args) {
// We Use Backslash \" Here
System.out.print( ("\" Hamidur Rahman Repon \" ");
}
}

Output :-

" Hamidur Rahman Repon "

Use of single quotation :- \'

Escape Sequences Meaning
\' Single Quote

\' : - The program used here I want to give a single quotation on both sides. If you want you can give a single quotation on one side. The use of (\ ') is given below as : -

File Name Main.java

Coped
package com.onlineashikhi;
public class Main {
public static void main(String[] args) {
// We Use Backslash \' Here
System.out.print( ("\' Hamidur Rahman Repon \' ");
}
}

Output :-

' Hamidur Rahman Repon '

Use of double backslash :- \\

Escape Sequences Meaning
\\ Backslash

\\ : - This is used to print a single backslash with double backslashes. If you give more double backslash the backslash will be created in that proportion. Remember that double backslashes create only one backslash. The use of (\\) is given below as : -

File Name Main.java

Coped
package com.onlineashikhi;
public class Main {
public static void main(String[] args) {
\\ We Use Double Backslash \\ Here
System.out.print( "\\ Hamidur Rahman Repon \\");
\\\\ We Use 4 Backslash \\\\ Here
System.out.print( "\\\\ Hamidur Rahman Repon \\\\");
}
}

Output :-

\ Hamidur Rahman Repon \
\\ Hamidur Rahman Repon \\

Hopefully, you have understood the Escape Sequence of Java programming very well. You must try to understand the use of Escape Sequence well. These will be needed when we are working on app development in Android Studio. If you want to learn Android apps development Click Here.
