If statement, C, C ++, Java

If the following if statement is availableProgramWill it be compiled?

Int X, Y = 10
If (x = y) x = y;

 

I have verified that C and C ++ can be compiled but cannot be compiled in Java, the reason is that a Boolean value must be returned for the condition expression in the brackets of the IF statement. The C language considers integer 0 as "false", and all values other than integer 0 as "true ". C ++ is compatible with C, so even if ("XXXX") can be compiled and determined to be true. However, Java strictly requires that a certain conditional expression in the IF (condition expression) Statement parentheses is a Boolean value, so the example program for this question cannot be compiled.
