Question

Java Program

Use for loop

1.) Write a program to display the multiplication table of a given integer. Multiplier and number of terms (multiplicand) must be user's input. Sample output: Enter the Multiplier: 5 Enter the number of terms: 3 5x0=0 5x1=5 5x2=10 5x3=15

2 Create a program that will allow the user to input an integer and display the sum of squares from 1 to n. Example, the sum of squares for 10 is as follows: (do not use math function) 1^2 +2^2+....10^2=385

Use Do-while

Write a do-wile loop that asks the user to enter two numbers. The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat, otherwise, it should terminate.

Continue

Write a program that reads an integer and display all the positive ODD numbers from 0 to n (integer entered by the user). Use CONTINUE branching statement to skip the display of EVEN in the result.

import java.util.Scanner;


public class MultiplicationTable {

        
        public static void main(String[] args) {
                Scanner in = new Scanner(System.in);
                
                System.out.println("Enter number whose"
                                + " multiplication table you want: ");
                int n = in.nextInt();
                
                System.out.println("Enter number of terms: ");
                int numTerms = in.nextInt();

                for(int i=1; i<=numTerms; i++) {
                        System.out.println(n + "\t*\t" + i +" \t = " + (n * i));
                }
                
                in.close();
        }

}
