核心代码：

public void bubbleSort(){        for(int i=0;i
     
      a[j+1])                    swap(j,j+1);            }        }    }    public void swap(int indexa,int indexb){        int temp = a[indexa];        a[indexa] = a[indexb];        a[indexb] = temp;    }
     

主要代码

class Array{    private int[] a;    private int length;        public Array(int max){        a = new int[max];        length = 0;    }    public void insert(int value){        a[length] = value;        length++;    }    public void dispaly(){        for(int i=0;i
