Coding Insertion sort dengan konsep OOP dan inputan user,,,,,,
Semoga berhasil yha teman,,,,

import java.io.*;
import javax.swing.JOptionPane;

class insert{
    static void printArray(int[] a){
        for (int i = 0; i < a.length; i++)
        System.out.print(" " + a[i]);
        System.out.print("\n");
    }
public static void insertion_sort(int array[], int n){
    for (int i = 0; i < n; i++){
      int j = i;
      int B = array[i];
      while ((j > 1) && (array[j-1] > B)){
        array[j] = array[j-1];
        j--;
      }
      array[j] = B;
    }  }

  public static void main (String args []) throws IOException{
       String get_value;
        int n =0;

    String strEntry;
        int i=0;
        int x = Integer.parseInt(JOptionPane.showInputDialog("Masukkan Index nya:"));
        int entry[] = new int[x];
        BufferedReader dataIn= new BufferedReader(new InputStreamReader(System.in));
        System.out.println();
        System.out.println();

        for( i =0 ; i < entry.length; i++){

            System.out.print("Masukkan Angka nya " + i +" : ");
            strEntry = dataIn.readLine();
            entry[i] = Integer.parseInt(strEntry);
        }
       System.out.println();
       System.out.println("== Angka Asli ==>");
        printArray(entry);

     insertion_sort(entry,entry.length );

        System.out.println("\n");
        System.out.println("== Angka Setelah Diurutkan ==>");
        printArray(entry);
