Convert Integer to numeric primitive data types example This example shows how an Integer object can be converted into below given numeric data types – Convert Integer to byte – Convert Integer to short – Convert Integer to int – Convert Integer to float – Convert Integer to double

public class IntegerToNumericPrimitiveTypesExample {

public static void main(String[] args) {
Integer intObj = new Integer(“10”);
//use byteValue method of Integer class to convert it into byte type.
byte b = intObj.byteValue();
System.out.println(b);

//use shortValue method of Integer class to convert it into short type.
short s = intObj.shortValue();
System.out.println(s);

//use intValue method of Integer class to convert it into int type.
int i = intObj.intValue();
System.out.println(i);

//use floatValue method of Integer class to convert it into float type.
float f = intObj.floatValue();
System.out.println(f);

//use doubleValue method of Integer class to convert it into double type.
double d = intObj.doubleValue();
System.out.println(d);
}
}

/*
Output of the program would be :
10
10
10
10.0
10.0
*/

/*Write a program to generate 5 Random nos. between 1 to 100, and it should not follow with decimal point. */

for(int i=1;i<=5;i++){

System.out.println((int)(Math.random()*100));
