Correct Answer:
Wrong Answer:
Percentage: %
- A. java.util
- B. java.lang
- C. java.awt
- D. java.io
Remarks:
Explanation:
The correct answer is:
(b) java.lang
The Character class is part of the java.lang package, which is automatically imported in every Java program. It provides various methods for character manipulation, such as isDigit(), isLetter(), and toUpperCase().
- A. z
- B. Z
- C. 122
- D. 154
Remarks:
Explanation:
The correct answer is:
(d) 154
Explanation:
In the expression:
System.out.println('Z' + 32);
-
The character
'Z'has an ASCII value of 90. -
The integer 32 is added to it:
90 + 32 = 122. -
Since both
'Z'(char) and32(int) are involved in an arithmetic operation,'Z'is promoted to an integer before addition. -
The result is 122, which is the ASCII value of
'z', but since no type casting is done, it prints the integer 122 instead of the character'z'.
So, the correct answer should be (c) 122, not (d) 154. Please verify your answer choices.
- A. 16
- B. 4
- C. 8
- D. 32
Remarks:
Explanation:
Each double in Java occupies 8 bytes, and the array contains 4 elements.
Total memory occupied = 8 bytes × 4 = 32 bytes
Correct answer: (d) 32
- A. 1
- B. 10
- C. 2
- D. 00
Remarks:
Explanation:
The output of \( 42 \div 6 \mod 2 \) is:
- (a) \( 1 \)
- (b) \( 10 \)
- (c) \( 2 \)
- (d) \( 0 \)
Let's break down the expression step by step:
\[ 42 \div 6 \mod 2 \]
Step 1: Division
\[ 42 \div 6 = 7 \]
Step 2: Modulus Operation
\[ 7 \mod 2 \]
The modulus operator (\%) gives the remainder when dividing 7 by 2.
\[ 7 \div 2 = 3 \text{ remainder } 1 \]
So,
\[ 7 \mod 2 = 1 \]

- B. Double.parse("25")
- C. Double.parseDouble("25")
- D. Double.parseDouble(25)
Remarks:
Explanation:
(c) Double.parseDouble("25")
Explanation: The parseDouble() method converts a String to a double. The correct syntax is Double.parseDouble("25").
- A. 3
- B. -6
- C. 6
Remarks:
Explanation:
The compareTo() method compares two strings lexicographically.
-
"ANGER".compareTo("ANGEL")compares characters at each position. -
'R' - 'L' = 82 - 76 = 6, so the result is6. -
Since "ANGER" comes after "ANGEL" lexicographically, the result should be positive.
-
Correct answer: (c)
6(Correction from previous choice!)
