1. Soal Pertama
Script :
import javax.swing.*;

public class tugas_bintang1 {
public static void main (String[] args) {
int x;
x=Integer.valueOf(JOptionPane.showInputDialog("Masukan banyak bintang ?"));
for (int i=1;i<=x;i++) {
    for (int j=1;j<=x;j++) {
             if (j<=i) System.out.print("*");
               else System.out.print(" "); }
                     System.out.println(); }
                             }
}

Output Program :

2. Soal Kedua
Script :
import javax.swing.*;

public class tugas_bintang2 {
public static void main (String[] args) {
int baris,x,y;
baris=Integer.valueOf(JOptionPane.showInputDialog("Masukan banyak bintang ?"));
x=baris+1;
for (int i=1;i<=baris;i++) {
for (int j=1;j<=baris;j++) {
   y=i+j; if (y<=x) System.out.print("*");
                        else System.out.print(" "); }
                           System.out.println(); }
