Homework Answers
Dear Student,
Here i have written complete Java code with the outputs KIndly Check it.
NOTE: Please note that all the program has been compiled and check using an online compiler.
Question No: 1
Program:a
---------------------------------------------------------------------------------------------------------------------------------------
public class Test
{
public static void main(String []arg)
{
int x = 1;
while (x != 15)
{
System.out.println ("Hello");
x++;
}
}
}
----------------------------------------------------------------------------------------------------------------------------------------
Output: Print Hello 14 times when the value of x is 15 program stops.below is the output.
Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello
----------------------------------------------------------------------------------------------------------------------------------------
Question No: 1
Program:b
----------------------------------------------------------------------------------------------------------------------------------------
public class Test
{
public static void main(String []arg)
{
int i = 1;
int sum = 0;
while (i <= 5)
{
sum = sum + i;
i++;
}
System.out.println("The value of sum is " + sum);
}
}
--------------------------------------------------------------------------------------------------------------------------------------
Output:2 The above program calculate the sum from 1 to 5 number and print the final result below is the output attached as a screen shot..
-----------------------------------------------------------------------------------------------------------------------------------------------
Question:2
Program:3
----------------------------------------------------------------------------------------------------------------------------------------------
import java.util.Scanner;
public class Leapyear{
public static void main(String[] args) {
int year;
Scanner console = new Scanner(System.in);
System.out.print("Enter a year : ");
year = console.nextInt();
if (year % 4 == 0) {
if (year % 100 == 0) {
if (year % 400 == 0) {
System.out.println("A leap year");
}
else {
System.out.println("Not a leap year");
}
}
else {
System.out.println("A leap year");
}
}
else
{
System.out.println("Not a leap year");
}
}
}
---------------------------------------------------------------------------------------------------------------------------------------
If you run the above code you will get the output as given below..If input is 2000.
Output:
So 2000 is a leap year.
--------------------------------------------------------------------------------------------------------------------------------------------
Question:2:
Program:1
-----------------------------------------------------------------------------------------------------------------------------------------
public class Test {
public static void main(String args[]) {
int x = 45;
int y = 10;
if( x == 30 ) {
if( y == 10 ) {
System.out.print("X = 30 and Y = 10");
else
System.out.print("X = 45 and Y = 10");
}
}
System.out.print("Nested
If");
----------------------------------------------------------------------------------------------------------------------------------------
Output: When you run the above program it results some syntax error. That are shown in the below attached screen shot.
----------------------------------------------------------------------------------------------------------------------------------------------
Question No:3
Program:1 below is the correct code snippet
---------------------------------------------------------------------------------------------------------------------------------------------
public class Test {
public static void main(String args[]) {
for (int i=1; i <= 5; i++)
{
for (int j=1; j <= 5; j++)
System.out.print (i*j + " ");
System.out.println();
}
}
}
