Question

Is there any error in the following code? It shows cant find symbol, symbol: class out location: class System. In the log, it show a lot of errors, including

java.lang.

Answer 1

In java does not work like this any behaviour you want to implement you must do it inside a block or a method

It needs to be inside an executable block of code to be executed. Otherwise there's no way to know when to execute it.

Remember that a class can only have attributes or methods.Attributes are the properties of the class and methods represent the behaviour of the class.So every implementation goes inside a method or a block.

The only things allowed outside method and constructor declarations are declarations of fields. Since

Scanner sc=new Scanner(System.in);
System.out.println("Enter the value of r");
int r=sc.nextInt();
System.out.println("enter the value h");
int h=sc.nextInt();

is not a field declaration, it's not allowed.
