Write a Java program to print the square with all zeros except the diagonal numbers pattern using for loop.
package Shapes3;
import java.util.Scanner;
public class SqaurewithDiagNum1 {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.print("Enter Square with Diagonal Numbers Side = ");
int rows = sc.nextInt();
System.out.println("Square with Numbers in Diaginal and Remaining 0's");
for (int i = 1; i <= rows; i++ )
{
for (int j = 1; j < i; j++ )
{
System.out.print("0 ");
}
System.out.print(i + " ");
for(int k = i; k < rows; k++)
{
System.out.print("0 ");
}
System.out.println();
}
}
}
It is another way of printing the square pattern with diagonal numbers and all the remaining items zeros in Java.
package Shapes3;
import java.util.Scanner;
public class SqaurewithDiagNum2 {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.print("Enter Square with Diagonal Numbers Side = ");
int rows = sc.nextInt();
System.out.println("Square with Numbers in Diaginal and Remaining 0's");
for (int i = 1; i <= rows; i++ )
{
for (int j = 1; j <= rows; j++ )
{
if(i == j)
{
System.out.print(i + " ");
}
else
{
System.out.print("0 ");
}
}
System.out.println();
}
}
}
Enter Square with Diagonal Numbers Side = 9

{

{
System.out.print(i + " ");
}
else
{
System.out.print("0 ");
}
j++;
}
System.out.println();
i++;
}
}
}

This Java program displays the square pattern of incremental diagonal numbers and all the remaining ones are zeros using a do while loop.
package Shapes3;
import java.util.Scanner;
public class SqaurewithDiagNum4 {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.print("Enter Square with Diagonal Numbers Side = ");
int rows = sc.nextInt();
System.out.println("Square with Numbers in Diaginal and Remaining 0's");
int i = 1;
do
{
int j = 1;
do
{
if(i == j)
{
System.out.print(i + " ");
}
else
{
System.out.print("0 ");
}
} while(++j <= rows);
System.out.println();
} while(++i <= rows);
}
}
