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.
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) |
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.
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.
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 |
