Where can I master java and know all about it? Is there a website or an app to do it?

Question

The title says it all

Answer 1

Start to read a book and watch video tutorials. If you want to learn something particular just Google it.

Answer 2

So many books are outdated , but they give you a good baseline. For example I would begin with 'Thinking in java'. In this book are covered the most important topics of java . Sometimes it may be difficult to understand some concepts , but you can find an easier explanation in web. One important note : try to practice every thing you've learned.

Answer 3

Java for what ? if pure Java, then Oracle site is a complete resource. if for Android development , then check out Android.developer site

int y = x % 2;
while (x <= 10) {
if (y == 0) {
System.out.println("Even");

}
x = x+1

}

Answer 15

when you say "int y ".... it means that you want to create a brand new variable (not assigning new value to an old variable)
and you can't have two variables with the same name ( inside one place)
