Bubble Algoritma Sortir di Java: Program & Contoh Penyortiran Array
James Hartman
Apa itu Bubble Urutkan?
BubblPengurutan adalah algoritma sederhana yang membandingkan elemen pertama array dengan elemen berikutnya. Jika elemen array saat ini secara numerik lebih besar daripada elemen berikutnya, elemen-elemen tersebut akan ditukar. Demikian pula, algoritma akan melintasi seluruh elemen array.
Dalam tutorial, kami akan membuat program JAVA untuk diimplementasikan Bubble Urutkan. Periksa keluaran kode yang akan membantu Anda memahami logika program.

package com.guru99;
public class BubbleSort {
public static void main(String[] args)
{
int arr[] ={860,8,200,9};
System.out.println("---Array BEFORE Bubble Sort---");
printArray(arr);
bubbleSort(arr);//sorting array elements using bubble sort
System.out.println("---Array AFTER Bubble Sort---");
printArray(arr);
}
static void bubbleSort(int[] array)
{
int n = array.length;
int temp = 0;
for(int i=0; i < n; i++) // Looping through the array length
{ System.out.println("Sort Pass Number "+(i+1));
for(int j=1; j < (n-i); j++)
{
System.out.println("Comparing "+ array[j-1]+ " and " + array[j]);
if(array[j-1] > array[j])
{
//swap elements
temp = array[j-1];
array[j-1] = array[j];
array[j] = temp;
System.out.println(array[j] + " is greater than " + array[j-1]);
System.out.println("Swapping Elements: New Array After Swap");
printArray(array);
}
}
}
}
static void printArray(int[] array){
for(int i=0; i < array.length; i++)
{
System.out.print(array[i] + " ");
}
System.out.println();
}
}
