True or False: Variable Declaration in Java

In Java, it is True that you must declare the types of variables. This is because Java is a statically typed language, meaning that the type of a variable is known at compile-time. Each variable must be declared with a specific data type (e.g., int, double, String, etc.), which defines the kind of data it can hold.

Here's a brief explanation:

1. Static Typing: In Java, the data type of variables is declared explicitly. For example:

   int age = 25;
   double salary = 50000.50;
   String name = "John";
   

2. Compile-Time Checking: The compiler uses the variable types to enforce rules about how those variables can be used, which helps catch errors early in the development process.

Thus, the declaration of variable types is indeed necessary in Java, making the statement true.
