Java Program for Half Diamond Star Pattern

Printing Half Diamond Star Pattern

In this program we’re going to code half diamond star pattern

In this program take a input from user and store in inside the variable as no and then  take for loop start from i=1 to i<=no and then take another for loop to print star which is start from j=1 to j<=i , and then take second another inner for loop start from i=no-1 to i>0 and then take j inner for loop start from i=1 to j<=i then print star statement  after that take line changement Algorithm:

• Enter the number as input from the user and store it in any variable.(‘no‘ in this case).
• Run a loop ‘no’ number of times to iterate through each of the rows. From i=1 to i<=no. The loop should be structured as for (int i = 1; i <= no; i++)
• Inside the main loop take another loop start with j=1 to j<=i and print above stars as System.out.print(“*”); after this inside loop take System.out.println(); to take a new line
• After the main loop take another loop to make downwards stars loop start with int i = no-1 to i >0; inside this take another loop to print stars for (int j = 1; j <=i; j++)

Code in Java:

import java.util.Scanner;
public class Pattern1 {

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter no");
int no=sc.nextInt();

for (int i = 1; i <= no; i++) {
for (int j = 1; j <= i; j++)
System.out.print("*");
System.out.println();
}
for (int i = no-1; i >0; i--) {
for (int j = 1; j <=i; j++)
System.out.print("*");
System.out.println();
}
}

}
