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:
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);
}
}
