Question

Write a Java code to complete the following operations:

(1) Define a double variable var1, initialize it with value 9.99

(2) Given two integer variables var2 and var3, write a statement that gives var3 a value that is 4 more than the value of var2.

(3) Define a double variable var4, initialize it with value 1234.56. Write a statement to change var4 so it will just hold one third (1/3) of the original value

(4) Given four double variables var5, var6, var7, var8. Define the fifth variable var9 which will be initialized with value that is 1/2 * var5 + 1/3 * var6 + 1/4 * var7 + 1/5 * var8

Answer 1

Explanation:

Here is the code which has all the parts of Java code completed and marked with the comments:

Code:

public class Main
{
   public static void main(String[] args) {
      
       //Part 1
       double var1 = 9.99;
      
       int var2, var3;
  
//Part 2
var3 = var2 + 4;
  
//Part 3
var4 = 1234.56;
  
var4 = (var4/3.0);
  
double var5, var6, var7, var8;
  
//Part 4
double var9 = (var5/2.0) + (var6/3.0) + (var7/4.0) + (var8/5.0);
   }
}
