Top Patterns in Java Code: How to Print Star(*)/Number/Character

Star Patterns in Java

First, let us begin with some of the basic and the commonly asked pattern program in Java.

Such as:

• Pyramid Star Program,
• Left Triangle Star Program,
• Right Triangle Star Program, etc.

Below Example prints the star(*), you can replace star to number or character as your wish to print.

1. Pyramid Program:

Code:

public class Main
{
public static void main(String[] args) {
        for (int i=0; i<5; i++)
        {
       for (int j=5;j>i;j--)
       {
            System.out.print(" ");
       }
       for (int j=0; j<=i; j++ )
        {
                System.out.print("*");
                System.out.print(" ");
        }
   System.out.println();
   }
    }
}

2. Left Triangle Star Pattern:

                        

Code:

public class Main
{
public static void main(String[] args) {
        for (int i=0; i<5; i++)
        {
       for (int j=2*(5-i);j>0;j--)
       {
            System.out.print(" ");
       }
       for (int j=0; j<=i; j++ )
        {
                System.out.print("*");
                System.out.print(" ");
        }
   System.out.println();
   }
    }
}

3. Right Triangle Star Pattern:

Code:

public class Main
{
public static void main(String[] args) {
        for (int i=0; i<5; i++)
        {
       for (int j=2*(5-i);j>0;j--)
       {
            System.out.print(" ");
       }
       for (int j=0; j<=i; j++ )
        {
                System.out.print("*");
                System.out.print(" ");
        }
   System.out.println();
   }
    }
}
