不兼容的操作数类型 int 和 int[]

Question

I am working on a Java application that recognizes the weight of a phone and writes the values to a database. However I have ran into the issue where the weight int isn't compatible to the values in the array 'phoneWeight' in the if statement. I was wondering if there is a simple way to overcome this?

    int weight = (data[4] & 0xFF) + (data[5] << 8);
    boolean phoneOnScale = false;
    int[] phoneWeight = {140, 150};

    System.out.println("My Weight: " + weight);

    if (weight == phoneWeight) {
        phoneOnScale = true;
        System.out.println("Phone is on scale");

Answer 1

This is an array of int's. You cannot compare an int to an array.

int[] phoneWeight = {140, 150};

You must check if weight is higher than mininum value and lower than maximum value, for phone to be on scale (between the two values), if I understood you right.

Answer 2

weight == phoneWeight is attempting to compare an int ( weight ), and an int[] ( phoneWeight ). This could never be true.

If you want to check if it's between the two numbers in the array, you'd have to explicitly check for that:

if(phoneWeight[0] <= weight && weight <= phoneWeight[1]) {

Use < instead of <= if you want the bounds to be exclusive. This also assumes that the first number is the lower bound, while the second number is the upper bound.
