The problem is that println is adding a newline after printing the * on each line. To fix this, use System.out.print instead of System.out.println in the inner loop:

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

Use System.out.print("*"); instead of println.
