Bubble Sort Program in Java

In this tutorial, we will share a java program to sort the elements of an array using the bubble sort algorithm. Bubble sort algorithm is the simplest sorting algorithm.

In this program, we traversed the first element of the array to the last element. We compare the current element with the next element if the current element is greater than next element, then it swapped.

Bubble Sort Program in Java

Copy the below Java program and execute it with the help Java Compiler.

public class BubbleSortExample {  
    static void bubbleSort(int[] arr) {  
        int n = arr.length;  
        int temp = 0;  
         for(int i=0; i < n; i++){  
                 for(int j=1; j < (n-i); j++){  
                          if(arr[j-1] > arr[j]){  
                                 //swap elements  
                                 temp = arr[j-1];  
                                 arr[j-1] = arr[j];  
                                 arr[j] = temp;  
                         }  
                          
                 }  
         }  
  
    }  
    public static void main(String[] args) {  
                int arr[] ={3,60,35,2,45,320,5};  
                 
                System.out.println("Array Before Bubble Sort");  
                for(int i=0; i < arr.length; i++){  
                        System.out.print(arr[i] + " ");  
                }  
                System.out.println();  
                  
                bubbleSort(arr);//sorting array elements using bubble sort  
                 
                System.out.println("Array After Bubble Sort");  
                for(int i=0; i < arr.length; i++){  
                        System.out.print(arr[i] + " ");  
                }  
   
        }  
}

public class BubbleSortExample {

static void bubbleSort(int[] arr) {

int n = arr.length;

int temp = 0;

for(int i=0; i < n; i++){

for(int j=1; j < (n-i); j++){

if(arr[j-1] > arr[j]){

//swap elements

temp = arr[j-1];

arr[j-1] = arr[j];

arr[j] = temp;

}

public static void main(String[] args) {

int arr[] ={3,60,35,2,45,320,5};

System.out.println("Array Before Bubble Sort");

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

System.out.print(arr[i] + " ");

}

System.out.println();

bubbleSort(arr);//sorting array elements using bubble sort

System.out.println("Array After Bubble Sort");

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

System.out.print(arr[i] + " ");

}

Program Output

Array Before Bubble Sort
3 60 35 2 45 320 5
Array After Bubble Sort
2 3 5 35 45 60 320
