    Default Bubble Sort errors

    hi, i'm a beginner java programmer and i have problems regarding my program. i can't make it work, it displays a lot of errors. i hope you can help me. this is my program:


    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();
    }
    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 < arrays.length; i++)
    {
    for(int j = 1; j < (n-1); j++)
    {
    if(arrays[j-1] > arrays[j])
    temp = arrays[j-1];

    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, "{ }".

    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.
