Question

What are the default values of a numeric primitive data type, char type, boolean type, and class types?

1) The default value of a numeric primitive data type is 0.
2) The default value of a char type is '\u0000'.
3) The default value of a boolean type is false.
4) The default value of a class type is null.

Answer 1

The default values of numeric primitive data types, char types, boolean types, and class types are explained.

Step-by-step explanation:

The default value of a numeric primitive data type is 0. For example, if you declare an int variable without initializing it, its default value will be 0.

The default value of a char type is ''. This is the null character in Unicode.

The default value of a boolean type is false. So, if you declare a boolean variable without initializing it, its default value will be false.

The default value of class types is null. If you declare an object variable without initializing it, its default value is a special reference value that represents null, indicating that the variable does not currently refer to an object.
