Convert Object to Int
In this section, we are going to learn to convert a numeric string
type Object into a primitive type int and Integer Object to primitive type int.
.
Code Description:
The following program converts numeric string type
object into primitive type int and Integer type object to primitive type int.
The parseInt() method of an Integer class takes a numeric string
object and returns the primitive type int value. Again, this program
converts an Integer object into a primitive type int using
the intValue() method.
Here is the code of this program:
import java.io.*;
import java.lang.*;
public class ObjectToInt{
public static void main(String[] args){
//Numeric string to primitive int
String Obj = "123";
int i = Integer.parseInt(Obj);
System.out.println("Numeric string to primitive int = " +i);
//Integer object to primitive int
Integer IntValue = 123;
int intValue = IntValue.intValue();
System.out.println("Integer object ot primitive int = "+intValue);
}
}
