延伸问题:如何找到一个数组中第N大元素并输出它所在的位置
public class FindThirdLarge { public static void getThirdLargeNumber(int [] array,int nLarge){ int count = 0;//大于某个数字的个数 int location = 0;//参考值的索引 int referenceValue = 0;//参考值 boolean flag = true;//循环执行标志 while(flag){ referenceValue = array[location]; for(int i=0;i<array.length;i++){ if( (i!=location) && (array[i]>referenceValue) ){ count +=1; } } if(count == (nLarge-1)){ flag = false; System.out.println("第"+nLarge+"大数字是:"+referenceValue+";位置在:"+location); }else{ count = 0; location+=1; flag = true; } } } public static void main(String[] args) { int ar [] = {3,6,4,9,5,2,8}; getThirdLargeNumber(ar,3); } }
