Answer 1

public class Triangles {

void pattern(char c) {

for (int i = 0; i < 5; i++) {

for (int j = 0; j <= i; j++)

System.out.print(c + " ");

System.out.println( );

}

}

void pattern(int a, int b) {

for (int i = 0; a <= b; i++) {

for (int j = 0; j <= i; j++, a++)

System.out.print(a + " ");

System.out.println( );

}

}

public static void main(String[ ] args) {

Triangles triangle = new Triangles( );

triangle.pattern('#');

triangle.pattern(2, 11);

}

}
