What are the consequences of declaring a variable count with type int?

Declaring a variable count with the type int in Java means it can store integer values in the range from -2,147,483,648 to 2,147,483,647. The implications of such a declaration:

• The variable cannot store fractional numbers or values outside the specified range.
• Attempting to assign a value outside the range will result in a compile-time error or overflow at runtime.
• The default value for int is 0 if the variable is a class field.

Example:

int count = 10;
count = count + 5; // correct
// count = 2147483648; // compile error, value out of range
