Sort (Bubble) - Java

With 1 Loop 

public class test123 {

public static void main(String[] args) {

int arr[] = {1,5,2,8,12,3,44};
int temp;

for(int i=0;i<arr.length-1;i++){
if(arr[i]>arr[i+1]){

arr[i]=arr[i+1];
arr[i+1]=temp;
i=i-1;
}

}
for(int k=0;k<arr.length;k++){
System.out.println(arr[k]);
}
}
}
