Computer Applications
Write a java program to accept an integer. From it create a new integer by removing all zeros from it. For example, for the integer 20180 the new integer after removing all zeros from it will be 218. Print the original as well as the new integer.
Answer
import java.util.Scanner;
public class Kboat
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter number: ");
int num = in.nextInt();
int idx = 0;
int newNum = 0;
int n = num;
while (n != 0) {
int d = n % 10;
if (d != 0) {
newNum += (int)(d * Math.pow(10, idx));
idx++;
}
n /= 10;
}
System.out.println("Original number = " + num);
System.out.println("New number = " + newNum);
}
}Output

Define a class to accept a number from user and check if it is an EvenPal number or not.
(The number is said to be EvenPal number when number is palindrome number (a number is palindrome if it is equal to its reverse) and sum of its digits is an even number.)
Example: 121 – is a palindrome number
Sum of the digits – 1+2+1 = 4 which is an even numberRewrite the following do while program segment using for:
x = 10; y = 20; do { x++; y++; } while (x<=20); System.out.println(x * y );
