Explanation: Boolean Object
- A. -128 to 127
- B. 0 to 255
- C. -32768 to 32767
- D. 0 to 65535
Remarks:
Explanation:
The byte data type in Java is an 8-bit signed integer that can represent values ranging from -128 to 127. This range allows the byte type to efficiently store small integer values within a compact memory space. The lower bound (-128) represents the smallest value that can be stored in a byte, while the upper bound (127) represents the largest value. This makes the byte type suitable for conserving memory when working with large arrays or collections of small integers where the full range of a larger integer type is unnecessary.
- A. -128 to 127
- B. -32768 to 32767
- C. 0 to 255

Remarks:
Explanation:
The long data type in Java is a 64-bit signed integer, ranging from -9223372036854775808 to 9223372036854775807. It is used for large integer values that exceed the range of int.
- A. 0
- B. 0.0
- C. null
- D. undefined
Remarks:
Explanation:
The default value of a byte datatype in Java is 0. If you declare a byte variable without assigning it a value, it will be initialized to zero automatically.
- A. 0
- B. 0.0
- C. null
- D. undefined
Remarks:
Explanation:
The default value of a short datatype in Java is 0. When you declare a short variable but do not initialize it explicitly, it will be set to zero by default.
- A. 0
- B. 0.0
- C. null
- D. undefined
Remarks:
Explanation:
In Java, the default value of an int datatype is 0. If you declare an int variable without assigning a value to it, it will automatically be initialized to zero.
- A. 0
- B. null
- C. undefined
- D. false
Remarks:
Explanation:
In Java, the default value of an Object datatype is null. If you declare an Object variable without initializing it explicitly, it will be set to null.
