Segitiga dan layang2 pake java

1. Segitiga

    public static void main(String[]args){

        int baris;
        int batasspasi=4;
        int batasbintang=1;

        for(baris=1;baris<=5;baris++){
            for(int spasi=1;spasi<=batasspasi;spasi++){

                System.out.print(" ");
            }
            for(int bintang=1;bintang<=batasbintang;bintang++){
                System.out.print("*");
            }
            System.out.println();
            batasspasi--;
            batasbintang+=2;
        }
    } 




2. Segitiga terbalik

     public static void main(String[]args){

        int baris;
        int batasspasi=1;
        int batasbintang=9;

        for(baris=1;baris<=5;baris++){
            for(int spasi=1;spasi<=batasspasi;spasi++){
                System.out.print(" ");
            }
            for(int bintang=1;bintang<=batasbintang;bintang++){
                System.out.print("*");
            }
            System.out.println();
            batasspasi++;
            batasbintang-=2;
        }
    }

3. Layang2


    public static void main(String[]args){

        int baris;
        int batasspasi=4;
        int batasbintang=1;

        for(baris=1;baris<=5;baris++){
            for(int spasi=1;spasi<=batasspasi;spasi++){
                System.out.print(" ");
            }
            for(int bintang=1;bintang<=batasbintang;bintang++){
                System.out.print("*");
            }
            System.out.println();
            batasspasi--;
            batasbintang+=2;
        }
        for(baris=1;baris<=5;baris++){
            batasspasi++;
            batasbintang-=2;
           
            for(int spasi=1;spasi<=batasspasi;spasi++){
                System.out.print(" ");
            }
            for(int bintang=1;bintang<=batasbintang;bintang++){
                System.out.print("*");
            }
            System.out.println();
        }
    }
