StringBuilder Class reverse() method
- reverse() method is available in java.lang package.
- reverse() method is used to reverse this character sequence by the reverse of the sequence.
- reverse() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
- reverse() method does not throw an exception at the time of reversing this character sequence.
Syntax:
public StringBuilder reverse();
Parameter(s):
- It does not accept any parameter.
Return value:
The return type of this method is StringBuilder, it returns a reference to this StringBuilder object.
Example:
// Java program to demonstrate the example
// of StringBuilder reverse() method of StringBuilder
public class Reverse {
public static void main(String[] args) {
// Creating an StringBuilder object
StringBuilder st_b = new StringBuilder("Java World ");
// Display st_b
System.out.println("st_b = " + st_b);
// By using reverse() method is to reverse the characters
// of this st_b object
st_b.reverse();
// Display reversible st_b
System.out.println("st_b.reverse() = " + st_b);
}
}
Output
st_b = Java World
st_b.reverse() = dlroW avaJ
