核心代码：

public void bubbleSort(){
        for(int i=0;i<length-1;i++){
            for(int j=0;j<length-i-1;j++){
                if(a[j]>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<length;i++)
            System.out.println("a["+i+"]="+a[i]);
    }
    public void bubbleSort(){
        for(int i=0;i<length-1;i++){
            for(int j=0;j<length-i-1;j++){
                if(a[j]>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;
    }
}
