最小堆删除方法永远运行

如何解决最小堆删除方法永远运行

大家好，我是编码初学者，我写了这个方法 delete from min-heap 但它一直在运行，当我使用调试器时，答案是正确的，但程序不会终止。

public void delete(){
        int temp= array[0];
        array[0]=array[counter-1];
        array[counter-1]=0;
        counter=counter-1;
        int parentIndex = 0;
        int leftChildindex = (parentIndex/2)+1;
        int rightChildindex = (parentIndex/2)+2;
        while ((array[parentIndex] >= array[leftChildindex] || array[parentIndex] >= array[rightChildindex]  )){
            
            if(array[leftChildindex]<array[rightChildindex]){
                int t =array[parentIndex] ;
                array[parentIndex]= array[leftChildindex] ;
                array[leftChildindex]=t;
                parentIndex=leftChildindex;
                leftChildindex = (parentIndex/2)+1;
                rightChildindex=(parentIndex/2)+2;
            }else {
                int t =array[parentIndex] ;
                array[parentIndex]= array[rightChildindex] ;
                array[rightChildindex]=t;
                parentIndex=rightChildindex;
                leftChildindex = (parentIndex/2)+1;
                rightChildindex=(parentIndex/2)+2;
            }
        }
    }
