Time limit exceeded(Bubble Sort)

Question

the code is compiled in my smartphone, and it says time limit exceeded. is there something wrong with the code?

import java.util.*;

public class Main
{
public static void main(String[] args)
{
int a[] = {6,5,4,7,3};
int i,x,temp;
for(i=0;i<a.length;i++){
for(x=0;x<a.length-1;x--){
if(a[i]>a[i+1]){
temp = a[i];
a[i]= a[i+1];
a[i+1] = temp;
}

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

System.out.println(a[i]);

}
}
}

Answer 1

Because this is not bubble sort :3 You should check your algorithm. I think it should be "if (a[x]>a[x+1])" and swap a[x], not a[i].

Answer 2

Thanks already got it, its a[x] instead of a[i] and instead of x-- its x++

Answer 3

i cant really tell your doing here but..

import. java.util.*; << not sure if this plays up somtimes i had a problem with it once

int [] a = << i usally put this before symbol

try putting ; at the end of ++ --

hope it helps
