Tampilan Segitiga pada JAVA

Dsini saya akan membantu anda yang mempunyai tugas untuk membuat segitiga pada JAVA .

1.         Pembuatan Segitiga Sama Kaki Terbalik dan Segitiga Siku-siku dengan menggunakan JAVA !

      Source Code :

import java.io.*;

public class Segitiga

{

public static String bacaInputan()

{

String baca="";

InputStreamReader input = new InputStreamReader (System.in);

BufferedReader buf = new BufferedReader (input);

try{

baca = buf.readLine();

}catch( IOException e )

{

System.out.println("Error !");

}

return baca;

}

public static void main(String[] args)

{

//digunakan untuk menangkap exception.

int a, b, c, n1, n2, pilih ;

do

{

System.out.println("+|--------------------------------------|+");

System.out.println("+|                                      |+");

System.out.println("+|       S  E  G  I  T  I  G  A         |+");

System.out.println("+|                                      |+");

System.out.println("+----------------------------------------+");

System.out.println("+|  MENU                                |+");

System.out.println("+|      1. Segitiga Sama Sisi Terbalik  |+");

System.out.println("+|      2. Segitiga Siku-siku           |+");

System.out.println("+|      3. Keluar                       |+");

System.out.println("+|--------------------------------------|+");

System.out.print("    PILIHAN :");

pilih=Integer.parseInt(bacaInputan());

switch(pilih)

{

case 1:

System.out.println("+----------------------------------------+");

System.out.println("+|                                      |+");

System.out.println("+|       S  E  G  I  T  I  G  A         |+");

System.out.println("+|                                      |+");

System.out.println("+|       S  A  M  A   S  I  S  I        |+");

System.out.println("+|                                      |+");

System.out.println("+----------------------------------------+");

System.out.print(" Masukkan tinggi segitiga : ");

n1=Integer.parseInt(bacaInputan());

System.out.println("");

for(a=1;a<=n1;a++)

{

for(b=1;b<=a;b++)

{

System.out.print(" ");

}

for(c=0;c>=(a-n1);c--)

{

System.out.print("*");

}

for(c=0;c<(n1-a);c++)

{

System.out.print("*");

}                                                 

System.out.println();

}

System.out.println("");

System.out.println("Membuat segitiga sama sisi, sisi="+n1);

break;

case 2:

System.out.println("+----------------------------------------+");

System.out.println("+|                                      |+");

System.out.println("+|       S  E  G  I  T  I  G  A         |+");

System.out.println("+|                                      |+");

System.out.println("+|      S  I  K  U    S  I  K  U        |+");

System.out.println("+|                                      |+");

System.out.println("+----------------------------------------+");

System.out.print(" Masukkan tinggi segitiga : ");

n2=Integer.parseInt(bacaInputan());

System.out.println("");

for(int i=1;i<=n2;i++)

{

for(int j=1;j<=i;j++)

{

System.out.print("*");

}

System.out.println();

}

System.out.println("");

System.out.println("Membuat segitiga siku-siku dengan sama kaki, alas="+n2+", dan tinggi="+n2);

System.out.println("");

break;

case 3:

System.exit(0);                                  

break;

default: System.out.println("SALAH INPUT");

break;

}

} while(true);

}

}

Output :
