Answer:
Point A: Always True
Point B: Sometimes false
Point C: Always False
Explanation:
In the given code snippet. Point A is the first statement within the While loop the statement System.out.println("Welcome to Java!"); will only be executed if the while condition evaluates to true.
At Point B, The statement count++ increases the value of the counter at every iteration, while it will be true for most occasions, at the last increament, this statement will be false that is at count=100, The condition will be false at this point just before program execution breaks out of the loop
Point C is outside of the loop, this happens when the given condition is no longer true.
Answer:
Constructor issue
Explanation:
When you look at the Class A, the constructor takes one argument as a parameter, a String.
A(String newS) {
s = newS;
}
However, in the main, the constructor does not take any argument as a parameter.
A a = new A();
That's why the code does not compile.
Execute this assignment from Scratch in the following way
Explanation:
1.For each thread, first Scratch sets the 'active thread' to that thread. Then, it executes each block one by one in the stack for the active thread. It will execute the entire stack all in one go if it can.
2.The Hide block is a Looks block and a Stack block. If the block's sprite is shown, it will hide the sprite — if the sprite is already hidden, nothing happens. This block is one of the simplest and most commonly used Looks blocks.
3.Scratch is used in many different settings: schools, museums, libraries, community centers, and homes.
4.Mitch Resnik, the creator of the super-simple Scratch programming language and head of the Lifelong Kindergarten group at the MIT Media Lab, gave a TEDx talk about the value of coding and computer literacy in early education.

Answer:
Relay
Explanation:
They both perform similar functions in terms of control of voltage and current but the relay would be better because although it cannot produce a variable output like that of an amplifier, it has the capacity to isolate its input from its output.
