Then, assign the value "156327.9804" to the double number. Then, assign the value of the double number to the other two variables using type casting. [...]

[...] Java Programming Part : 1 Objectives: To understand the concept of arithmetic operators, input statement, and type casting. PROGRAM-1: Program to demonstrate addition and subtraction operators. public class SumAndSub{ public static void main(String int result,no1, no2; no1 = 10; no2 = 20; result= no1 + no2; System.out.println(result); System.out.println(n2 – } } //PROGRAM-2: Program to demonstrate getting inputs using "Scanner" class. import java.util.Scanner; import the Scanner class public class Main{ public static void main(String Scanner myNo = new Scanner(System.in); int no1; float no2; System.out.println("Please enter two numbers:"); no1 = myNo.nextInt(); no2 = myNo.nextFloat(); System.out.println(no1 + no2); } } //PROGRAM-3:Program to demonstrate type casting.
