Study Notes
Declaring Variables in Java
- In Java, a variable is declared using the syntax "data_type variable_name;".
- The data type specifies the type of value the variable will hold, such as int, double, or String.
Assigning a Value to a Variable
- The process of assigning a value to a declared variable is called initialization.
- Initialization is done using the assignment operator (=) followed by the value to be assigned.
Initializing a Variable
- In Java, a variable is initialized by assigning a value to it when it is declared, using the syntax "data_type variable_name = value;".
- Initializing a variable sets its initial value, and it can be modified later in the program if needed.
