[Java][Resolved] Type mismatch: cannot convert from int to short

Incorrect sample:

public class static1{
    public static void main(String[] args){
        short s1 = 1;
        s1 = s1 + 1;
        System.out.println(s1);
    }
}

s1 +1 would return int, int can’t assign to short. Solution is converting the operation result from int type to short before assign to s1.

Correction:

public class static1{
    public static void main(String[] args){
        short s1 = 1;
        s1 = (short) (s1 + 1);
        System.out.println(s1);
    }
}

Remark :
It’s also work:

public class static1{
    public static void main(String[] args){
        short s1 = 1;
        s1 += s1;
        System.out.println(s1);
    }
}
