Java Program To Print Different Star Pattern

Print Different Star Pattern :

In Java language, You can simply print triangle shape using ‘for loop’ & also using ‘while loop’. Here, I will show you in simple way to print triangle in different shapes.

Pattern 1

Java Code :-

class StarTriangle
 {
 public static void main(String[ ] args)
 {
 int i,j,k;
 for(i=1; i<=5; i++)
 {
 for(j=4; j>=i; j--)
 {
 System.out.print(" ");
 }
 for(k=1; k<=(2*i-1); k++)
 {
 System.out.print("*");
 }
 System.out.println("");
 }
 }
 }

Pattern 2

Java Code :-

class Star
 {
 public static void main(String[ ] args)
 {
 int i, j, k;
 for(i=5;i>=1;i--)
 {
 for(j=5;j>i;j--)
 {
 System.out.print(" ");
 }
 for(k=1;k<(i*2);k++)
 {
 System.out.print("*");
 }
 System.out.println();
 }
 }
 }

 for(i=1; i<=6; i++)
 {
 for(j=1; j<i; j++)
 {
 System.out.print("*");
 }
 System.out.println();
 }
 }
 }

 {
 for(j=1;j<=i;j++)
 {
 System.out.print("*");
 }
 System.out.println();
 }
 }
 }

Pattern 5

Java Code :-

class Star
 {
 public static void main(String[ ] args)
 {
 int i, j, k;
 for(i=5;igt;=1;i--)
 {
 for(j=1;jlt;i;j++)
 {
 System.out.print(" ");
 }
 for(k=5;k>=i;k--)
 {
 System.out.print("*");
 }
 System.out.println();
 }
 }
 }

Pattern 6

Java Code :-

class Star
 {
 public static void main(String[ ] args)
 {
 int i, j, k;
 for(i=5;i>=1;i--)
 {
 for(j=5;j>i;j--)
 {
 System.out.print(" ");
 }
 for(k=1;k<=i;k++)
 {
 System.out.print("*");
 }
 System.out.println();
 }
 }
 }

Pattern 7

Java Code :-

class Star
 {
 public static void main(String[ ] args)
 {
 int i, j, k;
 for(i=1;i<=5;i++)
 {
 for(j=i;j<5;j++)
 {
 System.out.print(" ");
 }
 for(k=1;k<(i*2);k++)
 {
 System.out.print("*");
 }
 System.out.println();
 }
 for(i=4;i>=1;i--)
 {
 for(j=5;j>i;j--)
 {
 System.out.print(" ");
 }
 for(k=1;k<(i*2);k++)
 {
 System.out.print("*");
 }
 System.out.println();
 }
 }
 }
