Java基础—给定一个数组—输出数组中最大值_最大值下标—最小值_最小值下标

输出数组中最大值

public class ArrToBig {
    public static void main(String[] args) {
        int[] arr={-3,-6,-3,-10,-5,-4,2};
        int index = 0;
        for (int i=0;i< arr.length ; i++){
            index = (arr[index] <= arr[i]) ? i : index ;
        }
        System.out.println("最大值为："+arr[index]);
    }
}

输出数组中最大值下标

public class ArrToBigIndex {
    public static void main(String[] args) {
        int[] arr={-3,-6,-3,-10,-5,-4,2};
        int index = 0;
        for (int i=0;i< arr.length ; i++){
            index = (arr[index] <= arr[i]) ? i : index ;
        }
        System.out.println("最大值的下标为："+index);
    }
}

输出数组中最小值

public class ArrToNoBig {
    public static void main(String[] args) {
        int[] arr={-3,-6,3,-10,-5,-4,-2};
        int index = 0;
        for (int i=0;i< arr.length ; i++){
            index = (arr[index] >= arr[i]) ? i : index ;
        }
        System.out.println("最小值为："+arr[index]);
    }
}

输出数组中最小值下标

public class ArrToNoBigIndex {
    public static void main(String[] args) {
        int[] arr={-3,-6,3,-10,-5,-4,-2};
        int index = 0;
        for (int i=0;i< arr.length ; i++){
            index = (arr[index] >= arr[i]) ? i : index ;
        }
        System.out.println("最小值的下标为："+index);
    }
}
