# JAVA Program for Rhombus Star Pattern

## Printing Rhombus Star Pattern

In this JAVA program we will be coding a rhombus star pattern which will have n number of stars in it rows and n of stars in column hence it will be a n x n rhombus star pattern

## Printing Pattern

In this JAVA program we will be coding a rhombus star pattern which will have n number of stars in it rows and n of stars in column hence it will be a n x n rhombus star pattern

## Prerequisite:

Basic knowledge of Java language and loops

## Algorithm:

• Take the number of rows as input from the user and store it in any variable.(‘row‘ in this case).
• Take the number of coloum as input from the user and store it in any variable.(‘col‘ in this case).
• Run a loop ‘row’ number of times to iterate through each of the rows. From i=1 to i<=row. The loop should be structured as for                                     (int i=1; i<= row; i++)
•  Run a nested loop inside the main loop to print the spaces before the rhombus. From j=1 to j<=i. The loop should be structured as for( j=1; j<=i ; j++).
• Run another nested loop inside the main loop after the previous loop to print the stars in each column of a row. From j=1 to j<=col. The loop should be structured as for( j=1 ; j<=col ; j++).
• Move to the next line by printing a new line . System.out.print(“*”);
• After that take System.out.println(); at the end of main for loop

## 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 row and col");
int row = sc.nextInt();
int col = sc.nextInt();

for (int i=1; i<= row; i++) {
for (int j=1 ; j<=i ; j++)  // this loop is for printing spaces
System.out.print(" ");
for (int j=1 ; j<=col; j++) // this loop is for printing stars
System.out.print("*");
System.out.println();
}

}

}

public static void main(String[] args) {
System.out.println(“Enter Row and Column”);
Scanner scan=new Scanner(System.in);
int r=scan.nextInt();
int c=r*2+1;
for(int i=0;i<r;i++)
{
for(int j=0;j<c;j++)
{
if(i<=j&&j<=(c/2)+i)
{
System.out.print("*");
}
else
{
System.out.print(" ");
}
}

System.out.println();
}

Thank you prepinsta for publishing my code…
