Java valueOf() Method

Java Number Class

The valueOf() method returns the native Number object value of the given parameter, which can be a primitive data type, String, etc.

This method is a static method. It can take two parameters: one is a string and the other is a radix.

Syntax

This method has the following syntax formats:

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

Parameters

i -- Integer object's integer.

s -- Integer object's string.

radix -- The radix used in parsing string s, specifying the base number system.

Return Value

Integer valueOf(int i): Returns an Integer instance representing the specified int value.

Integer valueOf(String s): Returns an Integer object holding the value of the specified String.

Integer valueOf(String s, int radix): Returns an Integer object holding the value extracted from the specified String when parsed using the radix provided by the second parameter.

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);   // Using base 16

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

Compiling the above program will output the following:
