Default Values of Java Variables

In Java, if no initial value is explicitly assigned to a variable, Java will assign default values to these fields, which depend on the data type of the field.

Some common data types and their default values are:

• Integer types (such as int, long, short, byte), default value is 0.
• Floating-point types (such as float, double), default value is 0.0.
• Boolean type (boolean), default value is false.
• Character type (char), default value is '\u0000', representing the null character.
• Reference types (such as object references), default value is null.
