  •     BigDecimal to Integer
  •     Integer to BigDecimal
  •     Double to Integer
  •     Integer to double





package practiceJava;

import java.math.BigDecimal;

public class TypeConversion {
    public static void main(String[] args) {
        /*Convert String to Integer*/
        String name = "1234";
        Integer nm = Integer.parseInt(name);
        System.out.println("Name in Integer-->" + nm);
    }


    /*Convert Integer to String*/

    Integer a = 23;
    String num = a.toString();
    /*BigDecimal to Integer*/
    BigDecimal nom = new BigDecimal(450.9);
    Integer nomInt = nom.intValue();

    /*Integer to BigDecimal*/

    Integer cm = 45;
    BigDecimal cmBd = new BigDecimal(cm);
    
    /*Double to Integer*/

    double sys = 3;
    Integer sysInt = new Integer((int)sys);
   
   /*Integer to double*/
    Integer sd = 456;
    double sdDb = sd.doubleValue();
