how 25 output is come . without mentioned int ???


Java is strongly typed, this means variable need to be declared with explicit data type. Its a never ending debate among programmers, although the trend seems to go to strongly typed language at the moment

anyway, if you just want to print 25, you are not using declaring a variable or method, so you can just print 25.

However, if you wanted to do:

int myInt = 25;

you do need int.


Int = 2;
