Assignment Statements and Input

HOME

Develop code for assignment statements with expressions and determine the value that is stored in the variable as a result of these statements.

- Every variable must be assigned a value before it can be used in an expression. That value must be from a compatible data type. A variable is initialized the first time it is assigned a value. Reference types can be assigned a new object or null if there is no object. The literal null is a special value used to indicate that a reference is not associated with any object.
- The assignment operator = allows a program to initialize or change the value stored in a variable. The value of the expression on the right is stored in the variable on the left.
- During execution, an expression is evaluated to produce a single value. The value of an expression has a type based on the evaluation of the expression.
Develop code to read input.
- Input can come in a variety of forms, such as tactile, audio, visual, or text. The Scanner class is one way to obtain text input from the keyboard.
