Java - valueOf() Method

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

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
