The default value of a boolean variable is:

1. False
2. 0
3. false
4. True

Consider the array given below:

char ch[] = {'A','E','I','O', 'U'};

Write the output of the following statements:

System.out.println(ch[0]*2);:

1. 65
2. 130
3. 'A'
4. 0

The number of bytes occupied by a character array of four rows and three columns are:

1. 12
2. 24
3. 96
4. 48

Assertion (A): The boolean data type in Java can have only two possible values: true or false.

Reason (R): Boolean values in Java are stored as integers, with true represented by 1 and false by 0.
