Java - valueOf() Method


previous next AddThis Social Bookmark Button


Description:

The valueOf method returns the relevant Number Object holding the value of the argument passed. The argument can be a primitive data type, String etc.

This method is a static method. The method can take two arguments, where one is a String and the other is a radix.

Syntax:

All the variant of this method are given below:

static Integer valueOf(int i)
static Integer valueOf(String s)
static Integer valueOf(String s, int radix)

Parameters:

Here is the detail of parameters:

  • int : An int for which Integer representation would be returned.

  • String s : A String for which Integer representation would be returned.

  • int radix : This would be used to decide the value of returned Integer based on passed String.

Return Value :

  • valueOf(int i): This returns an Integer object holding the value of the specified primitive.

  • valueOf(String s): This returns an Integer object holding the value of the specified string representation.

  • valueOf(String s, int radix): This returns an Integer object holding the integer value of the specified string representation, parsed with the value of radix.

Example:

public class Test{ 
   public static void main(String args[]){
      
      Integer x =Integer.valueOf(9);
      Double c = Double.valueOf(5);
      Float a = Float.valueOf("80");               

      Integer b = Integer.valueOf("444",16);

      System.out.println(x); 
      System.out.println(c);
      System.out.println(a);
      System.out.println(b);
     }
}

This produces following result:

9
5.0
80.0
1092
