Thread: Bubble Sort errors

Please post your code in code tags.

Start by moving the bubbleSort() method outside the main() method. That should eliminate your compiler errors and give you code that you can test and improve.

Then check the if() clause inside the nested for loop. I believe you want brackets around the if() clause's 3 statements. Edit: Excuse me, not brackets, "[ ]", but braces, "{ }".

thanks for the help. if you don't mind, will you please provide me the proper methods for me to compare and serve as a guideline for my future projects? to be honest i am not much of a fast learner. anyway, thanks again

Not really, but we would be happy to help you write your own.
Please use code tags when posting code. Check out the Announcements page if you need help.
"i can't make it work, it displays a lot of errors" ...this tells us basically nothing.
What does the code do? What should it do instead? Provide actual output and desired output (with sample input if applicable)
If there are error messages, always include the full text of the error messages with the code and your question.
If you do not understand the error message, then say that is the question.

It seems like you've made a few errors in your code. Here's a corrected version:

public class BubbleSort1 {
public static void main(String[] args) {
int arrays[] = {5, 3, 2, 1, 51, 23};

System.out.print("Arrays Before Sorted: ");
for (int i = 0; i < arrays.length; i++) {
System.out.print(arrays[i] + " ");
}
System.out.println(); // Move this line outside the loop to print on a new line

bubbleSort(arrays);
System.out.print("Arrays Sorted: ");

for (int i = 0; i < arrays.length; i++) {
System.out.print(arrays[i] + " ");
}
}

private static void bubbleSort(int[] arrays) {
int n = arrays.length;
int temp = 0;
for (int i = 0; i < n; i++) { // Change the loop condition to n
for (int j = 1; j < (n - i); j++) { // Change the loop condition to (n - i)
if (arrays[j - 1] > arrays[j]) {
temp = arrays[j - 1];
arrays[j - 1] = arrays[j];
arrays[j] = temp;
}
}
}
}
}
