What is ++== in Java?

Question

1. Searched this site, found no reference.

2. Test code:

   int[] test = {0, 1, 2, 3};
   System.out.println("test1[3] ++== 0 is " + (test[3] ++== 0));
   

3. Result:

test1[3] ++== 0 is false

So it must be some sort of logical operator but I have not been able to find any documentation. Searching the Internet yielded no reference.

Please help? Thanks in advance.

Answer 1

The way the text is presented looks like it would be a special case ++==, but in fact you should read it as follows:

test[3]++ == 0

Basically, the result of test[3]++ will be compared (i.e ==) with 0.

And this basically reads as (test[3]=3) == 0, which is false.

The ++ is a postfix operator which is shortcut for value = value + 1.

The == is a comparison between two values.

The text is just badly formatted, that's all.

Answer 2

++ and == are two independent operators. ++ is post-incrementing the value of test[3], then that is being compared to 0.
