java bubble sort method code example
Example 1: bubble sort java
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;
}
}
}
}
Example 2: bubble sort in java
public static void bubbleSort(int arr[])
{
for (int i = 0; i < arr.length; i++) //number of passes
{
//keeps track of positions per pass
for (int j = 0; j < (arr.length - 1 - i); j++) //Think you can add a -i to remove uneeded comparisons
{
//if left value is great than right value
if (arr[j] > arr[j + 1])
{
//swap values
int temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
}
Example 3: bubble sort java
public class DemoBubbleSort
{
void bubbleSort(int[] arrNum)
{
int num = arrNum.length;
for(int a = 0; a < num - 1; a++)
{
for(int b = 0; b < num - a - 1; b++)
{
if(arrNum[b] > arrNum[b + 1])
{
int temp = arrNum[b];
arrNum[b] = arrNum[b + 1];
arrNum[b + 1] = temp;
}
}
}
}
void printingArray(int[] arrNum)
{
int number = arrNum.length;
for(int a = 0; a < number; ++a)
{
System.out.print(arrNum[a] + " ");
System.out.println();
}
}
public static void main(String[] args)
{
DemoBubbleSort bs = new DemoBubbleSort();
int[] arrSort = {65, 35, 25, 15, 23, 14, 95};
bs.bubbleSort(arrSort);
System.out.println("After sorting array: ");
bs.printingArray(arrSort);
}
}
