Here are some examples of Java programs to create pyramid and pattern:

1. Pyramid of stars

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

Output:

* 
    * * 
   * * * 
  * * * * 
 * * * * *

2. Pyramid of numbers

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

Output:

1 
   1 2 
  1 2 3 
 1 2 3 4 
1 2 3 4 5

3. Pattern of stars

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

Output:

* 
* * 
* * * 
* * * * 
* * * * *

4. Pattern of numbers

public class NumberPatternExample {
    public static void main(String[] args) {
        int rows = 5;
        for (int i = 1; i <= rows; i++) {
            for (int j = 1; j <= i; j++) {
                System.out.print(j + " ");
            }
            System.out.println();
        }
    }
}

Output:

1 
1 2 
1 2 3 
1 2 3 4 
1 2 3 4 5

These are just a few examples of the types of patterns that can be created with Java programs. You can modify the code to create different types of patterns by changing the loop conditions and the characters that are printed to the console.
