Programming In Java

Step 1: Understanding byte storage.
In basic computer representation, each character generally occupies 1 byte of storage in simple character encoding. So, to find which option occupies 2 bytes, we count the number of characters.
Step 2: Analyze each option.

• 25: This contains two digits, but in such school-level questions it is usually treated as a numeric value rather than a two-character text entry.
• AM: This contains two characters, A and M. Hence, it occupies 2 bytes.
• 35.2: This has more than two characters.
• \textbackslash\textbackslash: This representation does not match the expected two-byte text answer in the given context.

Step 3: Identify the best answer.
Among the given options, AM clearly consists of two characters. Since each character occupies 1 byte, the total storage required is:
Step 4: Conclusion.
Therefore, the option that occupies 2 bytes of storage is AM.
Final Answer:AM.

Step 1: Understand what an access specifier is.
An access specifier controls the visibility or accessibility of classes, methods, variables, and constructors in object-oriented programming. It decides from where a member can be accessed.
Step 2: Recall the common access specifiers in Java.
In Java, the commonly used access specifiers are:

• public -- accessible from everywhere.
• private -- accessible only within the same class.
• protected -- accessible within the same package and also in subclasses.
• default -- when no access specifier is written, it is called default or package-private access.

Step 3: Compare the given options.

• (A) private: This is a valid access specifier.
• (B) protected: This is also a valid access specifier.
• (C) package: This is not an actual keyword used as an access specifier. The correct term is default access or package-private access, but package itself is not an access specifier keyword.
• (D) public: This is a valid access specifier.

Step 4: Conclusion.
Therefore, the option which is \underline{NOT} an access specifier is package.
Final Answer:package.

Step 1: Understand the two repeating motions shown in the picture.
The picture shows two repeating processes happening together:

• The earth rotates on its own axis once every day.
• The earth revolves around the sun once every year.

This means one repeated motion is happening inside another larger repeated motion.
Step 2: Relate this to programming logic.
In programming, when one loop works inside another loop, it is called a nested loop. Here, daily rotation can be compared to the inner loop, while yearly revolution can be compared to the outer loop. So, many rotations happen during one revolution, just like many inner loop executions happen during one outer loop cycle.
Step 3: Compare with the given options.

• (A) Array: Incorrect. An array is a collection of elements, not a repeated process.
• (B) Condition: Incorrect. A condition checks true or false, but the picture shows repetition.
• (C) Nested loop: Correct. One repetitive activity is taking place within another repetitive activity.
• (D) While loop: Incorrect. A while loop is a single loop, not a loop inside another loop.

Step 4: Conclusion.
Therefore, the concept shown in the picture is nested loop, because one cycle of motion takes place repeatedly inside another larger cycle.
Final Answer:Nested loop.

Step 1: Understanding the term JVM.
JVM is a very common term in computer science, especially in Java programming. It refers to the environment that allows Java programs to run on different systems.
Step 2: Expanding the abbreviation.
The letters in JVM stand for:
J = Java
V = Virtual
M = Machine
So, JVM means Java Virtual Machine.
Step 3: Checking the options.

• (A) Java Visible Machine: Incorrect. ``Visible'' is not the correct word.
• (B) Java Virtual Mode: Incorrect. JVM does not stand for Virtual Mode.
• (C) Java Virtual Machine: Correct. This is the standard full form of JVM.
• (D) Java Visible Mode: Incorrect. This is not related to Java execution.

Step 4: Conclusion.
Therefore, the correct full form of JVM is Java Virtual Machine.
Final Answer:Java Virtual Machine.

Step 1: Understand the meaning of accumulator.
An accumulator is a variable that stores a running total. It usually appears on both sides of an assignment statement because its old value is used and then updated with a new value.
Step 2: Examine the given statement.
The statement is: Here, the old value of c is taken first. Then some new quantity is added to it. After that, the result is stored again in c.
Step 3: Identify the accumulator variable.
Since c is the variable that keeps collecting the updated value repeatedly, it acts as the accumulator. The other variables , , and are only used in the calculation and are not storing the running total.
Step 4: Conclusion.
Therefore, the accumulator variable in the given statement is c.
Final Answer:c.
