Example

The following example shows the usage of java.lang.Integer.toString() method.

package com.tutorialspoint;

import java.lang.*;

public class IntegerDemo {

   public static void main(String[] args) {

   Integer i = new Integer(10);
   
      // returns a string representation of the specified integer with radix 10
      String retval = i.toString(30, 10);
      System.out.println("Value = " + retval);
 
      // returns a string representation of the specified integer with radix 16
      retval = i.toString(30, 16);
      System.out.println("Value = " + retval);

      // returns a string representation of the specified integer with radix 8
      retval = i.toString(30, 8);
      System.out.println("Value = " + retval);
   }
} 

Let us compile and run the above program, this will produce the following result −

Value = 30
Value = 1e
Value = 36
