Question

i have no clue what is wrong with this. please help. i think its something wrong with my methods...
public class bubbleSort4{
  public static void main (String []args){
    bubbleSort4(x);
    for (int y=0; y<x.length-1; y+=1){
      System.out.println(work[y]);
    }//end of for
  }//end of main
public static void bubbleSort4(int[] x) {
  x={23, 36, 47, 2, 34, 5, 6, 7, 8, 9, 100, 6};
  int newLowest = 0;            // index of first comparison
    int newHighest = x.length-1;  // index of last comparison
    while (newLowest < newHighest) {
        int highest = newHighest;
        int lowest  = newLowest;
        newLowest = x.length;    // start higher than any legal index
        for (int i=lowest; i<highest; i++) {
            if (x[i] > x[i+1]) {
               // exchange elements
               int temp = x; x[i] = x[i+1]; x[i+1] = temp;
if (i<newLowest) {
newLowest = i-1;
if (newLowest < 0) {
newLowest = 0;
}//end of if
} else if (i>newHighest) {
newHighest = i+1;
}//end of else if
}//end of if
}//end of for
}//end of while
}//end method bubbleSort4
}//end of class

Answer 1

fixed it up! thanks a lot guys
public class bubbleSort4{
  public static void main (String []args){
    int [] arrayx= {23, 36, 47, 2, 34, 5, 6, 7, 8, 9, 100, 6};
    bubbleSort4(arrayx);
    for (int y=0; y<arrayx.length-1; y+=1){
      System.out.println(arrayx[y]);
    }//end of for
  }//end of main
public static void bubbleSort4(int[] arrayx) {
  int newLowest = 0;            // index of first comparison
    int newHighest = arrayx.length-1;  // index of last comparison
    while (newLowest < newHighest) {
        int highest = newHighest;
        int lowest  = newLowest;
        newLowest = arrayx.length;    // start higher than any legal index
        for (int i=lowest; i<highest; i++) {
            if (arrayx[i] > arrayx[i+1]) {
               // exchange elements
               int temp = arrayx; arrayx[i] = arrayx[i+1]; arrayx[i+1] = temp;
if (i<newLowest) {

if (newLowest < 0) {
newLowest = 0;
}//end of if
} else if (i>newHighest) {
newHighest = i+1;
}//end of else if
}//end of if
