variable Initialization and Default Values

In this problem, you will create a program that declares and initializes variables of each data type (int, double, boolean, char, String) and displays their initial values to standard output.

Learning Objective: Understand the necessity of local variable initialization and default values for data types

Overview

In Java, local variables must be initialized before use. Each data type has standard initial values.

Specifications

• Declare and initialize variables of each data type
• Display initial values for int, double, boolean, char, String

Output Format

int: 0
double: 0.0
boolean: false
char: A
String: empty
