    Default need help with bubbe sort

     
     
    int numbers[] = new int[]{10,41,21,24,34,15,40,12,32,23,13,25,30,31,22,33,14,35,20,11};
                    for(int i=0; i < numbers.length; i++){
     
     
                             if(numbers[i]%2 == 0){
                                    System.out.println(numbers[i] + " is even number.");
                                 java.util.Arrays.sort(numbers);
                              //  java.util.bubbleSort(numbers);(the problem is here...
     
     
     
     
                            }
     
                             {
                                    System.out.println(numbers[i] + " is odd number.");
                                    java.util.Arrays.sort(numbers);
                                }
                    }


    i need explanation how to use bubble sort coding...i did learn from tutorial but abit confusing...

    --- Update ---

    the other question is....about "binary search in even arr and find out the location of number 32 and display the location of the number 32 on the screen"..

    What are you confused about in using/writing a bubble sort algorithm? It's probably one of the best documented sorting approaches on the Internet, so you might want review more than one tutorial/discussion before giving up.

    Your other question looks more like a statement taken from an assignment than a question. What's your question about it?

    Write out the steps necessary to implement the sort, then translate that to syntax. If you get stuck, post your list of steps and code here with your question. We do not provide answers in code on the forum.
    Explain exactly what it is you are stuck on. "How to implement bubble sort" is not specific, it is the whole topic.

    it say: method search ElementLinear in class LinearSearch cannot be applied to given type;

    required:int[], int

    found:java.ulti.list<java.lang.integer>,int

    reason:actual argument java.ulti.lst<java.lang.integer>cannot be converted to int[] by method invocation conversion

    That means the method requires int[], but was given List<Integer>
    An array of int is not the same thing as a List of Integer
    In the code even and odd are both variables of type List<Integer>. Change them to int arrays ( int[] ) or convert them to int arrays for the method call
    Off topic.. what happened to doing bubble sort?

    Default Re: need help with bubbe sort

    ok i try first....then for the bubble sort i change to collection sort..it abit hard for me to implement the bubble sort...

    --- Update ---

    In the code even and odd are both variables of type List<Integer>. Change them to int arrays ( int[] ) or convert them to int arrays for the method call
      List<Integer> odd = new ArrayList<Integer>();
      List<Integer> even = new ArrayList<Integer>();
     
     
      System.out.println("Linear Search Index : "   + linearSearch.searchElementLinear(odd, toSearch));  
      System.out.println("Binary Search Index : "   + binarySearch.searchElementBinary(even, toSearch));


    --- Update ---

    this what i comeout...
     
    int odd1[] = {11, 13, 15, 21, 23, 25, 31, 33, 35, 41};
     int even1[] = {10, 12, 14, 20, 22, 24, 30, 32, 34, 40};
     int toSearch = 31; 
      int toSearch2 =32;
     
     
    System.out.println("Linear Search Index : "   + linearSearch.searchElementLinear(odd1, toSearch));  
     System.out.println("Binary Search Index : "   + binarySearch.searchElementBinary(even1, toSearch2));


    --- Update ---

    the output..

    Even number :[10, 12, 14, 20, 22, 24, 30, 32, 34, 40]
    Odd number :[11, 13, 15, 21, 23, 25, 31, 33, 35, 41]
    Linear Search Index : 6
    Binary Search Index : 7
