Another dumb question I came across online - I wish they get their questions more serious & mature before throwing at candidates.

public class PrintStars {
   public static void main(String[] args) {
      int i,j,n;
      n = Integer.parseInt(args[0]);//no of rows to print
      for(i=0;i<n;i++){
         for(j=0;j<=i;j++){
            System.out.print("*");
         }
      System.out.println("");
      }
   }
}

public class printStars {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		for(int i=1; i<5; i++) {
			for(int j=1; j<=i; j++) {
				System.out.print("*");
			}
			System.out.println();
		}
	}

}

public static void printPyramid(int height){
		for (int row =0 ;row <height ; row++ )
		{
			for (int i= 0 ;i< row ;i++ )
			{
				System.out.print("*");
			}
			System.out.println("");
		}
	}

public class PrintStars {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int n = 1;
		String str = ""; 
		
			for(int i = 1;i <= 4; i++)
			{	
				while(n <= i)
				{
					str += "*";
					n++;
					
				}
				
				System.out.println(str);
				str = "";
				n = 1;	
			}
					
		}
	}

Seriously , this question was asked in your interview ?

package gao.zone.study;

import java.util.Arrays;

public class PrintAsteriskTraingle {

	public static void main(String[] args) {
		print(1, 4, 1);
	}

	private static void print(int min, int max, int step) {
		for (int i = min; i <= max; i += step) {
			printLine(i);
		}
	}

	private static void printLine(int length) {
		char[] chars = new char[length];
		Arrays.fill(chars, '*');
		System.out.println(String.valueOf(chars));
	}
}

public class PrintStars {
String text = "*";
for(i=0;i<5;i++){
System.out.print(text);
text=text+"*";
}
}
}

...was this a serious question? I may have laughed if they asked it.

import java.lang.StringBuilder;

public class Test {
	public static void main(String[] args) {
		StringBuilder sb = new StringBuilder();
		for (int itr = 0; itr < 4; itr++) {
			sb.append("*");
			System.out.println(sb.toString());
		}
	}
}

import java.util.Scanner;

public class StarTree {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);
System.out.println("Enter number .... ");
int noofrows = input.nextInt();

for (int i = 0; i < noofrows; i++) {
for (int j = 0; j <=i; j++) {
System.out.print("* ");
}
System.out.println("\n");
}
}
}
