Java - String valueOf() Method

Description

This method has the following variants, which depend on the passed parameters. This method returns the string representation of the passed argument.

• valueOf(boolean b) − Returns the string representation of the boolean argument.
• valueOf(char c) − Returns the string representation of the char argument.
• valueOf(char[] data) − Returns the string representation of the char array argument.
• valueOf(char[] data, int offset, int count) − Returns the string representation of a specific subarray of the char array argument.
• valueOf(double d) − Returns the string representation of the double argument.
• valueOf(float f) − Returns the string representation of the float argument.
• valueOf(int i) − Returns the string representation of the int argument.
• valueOf(long l) − Returns the string representation of the long argument.
• valueOf(Object obj) − Returns the string representation of the Object argument.

Syntax

Here is the syntax of this method −

static String valueOf(boolean b) 
or 
static String valueOf(char c) 
or
static String valueOf(char[] data) 
or
static String valueOf(char[] data, int offset, int count) 
or
static String valueOf(double d) 
or
static String valueOf(float f) 
or
static String valueOf(int i)
or
static String valueOf(long l)
or
static String valueOf(Object obj) 

Parameters

• See the description.

Return Value

• This method returns the string representation.

Example

import java.io.*;
public class Test {

   public static void main(String args[]) {
      double d = 102939939.939;
      boolean b = true;
      long l = 1232874;
      char[] arr = {'a', 'b', 'c', 'd', 'e', 'f','g' };

      System.out.println("Return Value : " + String.valueOf(d) );
      System.out.println("Return Value : " + String.valueOf(b) );
      System.out.println("Return Value : " + String.valueOf(l) );
      System.out.println("Return Value : " + String.valueOf(arr) );
   }
}

This will produce the following result −

Output

Return Value : 1.02939939939E8
Return Value : true
Return Value : 1232874
Return Value : abcdefg
