简单的java为什么变量不会改变？

Question

public class Practice {
    public static void main( String args[] )
    {
        int lowest= 5;
        int sum = 2;
        if (lowest>sum){
            sum=lowest; 
        }
        System.out.println( lowest );
    }   
}

From this code I, get 5 but shouldn't I get 2? how should I change the code to make it equal to 2 instead of "sum=lowest;"?

Answer 1

Because assignment is the other way around. It is like:

variable = new value;

So, you want:

lowest = sum;

Answer 2

I'm not sure what you're trying to do, but you never alter the value of lowest , but you assign lowest to sum

Do you mena to print the value of sum ?

Answer 3

Change

if (lowest > sum){
    sum = lowest; 
}

to

if (lowest > sum){
    lowest = sum; 
}

if you are trying to get lowest to be equal to 2 .

Answer 4

If you want 2 , just do:

    if (lowest>sum){
        lowest=sum; 
    }

Answer 5

lowest = sum.

by doing "sum = lowest" you are assigning the value of lowest to sum. Assignments work right to left
