Java – Convert Integer to Long

In Java, we can use Long.valueOf() to convert an Integer to a Long

package com.mkyong.example;

public class TestInteger {

    public static void main(String[] args) {

        Integer num = 1;

        System.out.println(num);            // 1

        Long numInLong = Long.valueOf(num);

        System.out.println(numInLong);      // 1

    }
}
