Description
- The valueOf () method - returns the corresponding numeric object containing the value of the passed argument, in simple words - converts it to the desired data type.
- The argument can be converted to int, double, float and other data types, for example, you can convert a string to a number.
- The valueOf () method in Java is a static method. A method can take two arguments, where one is a string and another number system.
Syntax
All variants of the method are given below:
static Integer valueOf(int i)
static Integer valueOf(String s)

Options
Detailed information about the parameters:
- i - int, for which the integer representation will be returned.
- s - String for which the integer representation will be returned.
- radix - can be used to decide what integer value will be returned to based on the String passed.
Return value
- valueOf (int i): returns an integer object containing the value of the identified type.
- valueOf (String s): returns an Integer object containing the value of the identified string representation.
- valueOf (String s, int radix): returns an integer object taking an integer value of the identified string illustration, described with the value of the integer system.
Sample Code
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);
