The question is in the attachment.Write the program in JAVA language.
Hoping for correct program.
Please do not write if you do not know.

check it :
import java.io.*;
// Java code to demonstrate star patterns
public class GeeksForGeeks
{
// Function to demonstrate printing pattern
public static void printStars(int n)
{
int i, j;
// outer loop to handle number of rows
// n in this case
for(i=0; i<n; i++)
{
// inner loop to handle number of columns
// values changing acc. to outer loop
for(j=0; j<=i; j++)
{
// printing stars
System.out.print("* ");
}
// ending line after each row
System.out.println();
}
}
// Driver Function
public static void main(String args[])
{
int n = 5;
printStars(n);
}
}
Output:

hope it helps u..
Sample Program to print pattern in Java:
import java.util.*;
class Brainly
{
public static void main(String args[])
{
int i,j,k,n;
Scanner demo = new Scanner(System.in);
System.out.println("Enter the number of rows: ");
n = demo.nextInt();
System.out.println("\n");
for( i = 1; i <=n; i++)
{
for( j = 1; j <i; j++)
{
System.out.print(" ");
}
for(k = i; k <=n; k++)
{
System.out.print("*");
}
System.out.println();
}
for(i = n - 1; i >= 1; i--)
{
for(j = 2; j <=i; j++)
{
System.out.print(" ");
}
for(k = i; k <= n; k++)
{
System.out.print("*");
}
System.out.println();
}
}
}
Hope it helps! -------- Good Luck!
