Java ValueOf() Method

Description

The valueOf method revisits the pertinent Number Object possessing the value of the argument bypassed. The argument can be a prehistoric data type, String, etc. This process is a still method. The method can pick two arguments, where the initial is a String and the next is a radix.

Syntax

Following are all the variants of this method:

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

Parameters

Here is the detail of parameters −

• i − An int for which Integer representation would be returned.
• s − A String for which Integer representation would be returned.
• radix − This would be used to decide the value of returned Integer based on the 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 will produce the following result:

Output
