perkalian matrik di java - Sobat indpras berikut codingnya

package bel_array; /*  * @author indpras  */ import java.util.Scanner; public class perkalian_matrik {     void Show()     {         Scanner masuk = new Scanner (System.in);         System.out.println ("Masukan banyak baris dan kolom matriks 1");         System.out.print ("masukkan baris : ");         int baris1 = masuk.nextInt ();         System.out.print ("masukkan kolom : ");         int kolom1 = masuk.nextInt ();         System.out.println ();          System.out.println ("Masukan banyak baris dan kolom matriks 2");         System.out.print ("banyak baris : ");         int baris2 = masuk.nextInt ();         System.out.print ("banyak kolom : ");         int kolom2 = masuk.nextInt ();          if(kolom1 == baris2)         {          int Matriks1[][]=new int[baris1][kolom1];         int Matriks2[][]=new int[baris2][kolom2];         int hasil[][]=new int[baris1][kolom2];         System.out.println("Matrik 1");         for (int i=0;i<baris1;i++)         {             for (int j=0;j<kolom1;j++)             {                 System.out.print("Masukan nilai matriks 1 :");                 //System.out.print("Masukkan nilai baris ke"+i+" kolom ke-"+j+" = ");                 Matriks1[i][j]=masuk.nextInt();             }         }          System.out.println();                  System.out.println("Matriks 2");         for (int i=0;i<baris2;i++)         {             for (int j=0;j<kolom2;j++)             {                 System.out.print("Masukan nilai matriks 2 :");                 Matriks2[i][j]=masuk.nextInt();             }         }         System.out.println();         System.out.println ("Matrik 1");         for (int i=0;i<baris1;i++)         {             for (int j=0;j<kolom1;j++)             {                 if (j==0)                 {                     System.out.print("| ");                 }                 System.out.print(Matriks1[i][j]+" ");                 if (j==kolom1-1)                 {                     System.out.print("|");                 }             }             System.out.println();         }         System.out.println();         System.out.println ("Matrik 2");         for (int i=0;i<baris2;i++)         {             for (int j=0;j<kolom2;j++)             {                 if (j==0)                 {                     System.out.print("| ");                 }                 System.out.print(Matriks2[i][j]+" ");                 if (j==kolom2-1)                 {                     System.out.print("|");                 }             }             System.out.println();         }          int m=0;         for (int i=0;i<baris1;i++)         {             for (int j=0;j<kolom2;j++)             {                 m=0;                 for (int k=0;k<baris2;k++)                 {                     m+=Matriks1[i][k]*Matriks2[k][j];                 }                 hasil[i][j]=m;             }         }          System.out.println();         System.out.println("Hasil");         for (int i=0;i<baris1;i++)         {             for (int j=0;j<kolom2;j++)             {                 if (j==0)                 {                     System.out.print("| ");                 }                 System.out.print(hasil[i][j]+" ");                 if (j==kolom2-1)                 {                     System.out.print("|");                 }             }             System.out.println();         }         }         else         {             System.out.println("Matrik tak bisa dikalikan");         }     }      public static void main(String[] args) {         perkalian_matrik matrik=new perkalian_matrik();         matrik.Show();     } }
