Making a class's instance variables public and its methods private and accessing those instance variables only through the class's methods and properties facilitates debugging, because problems with data manipulations are localized to the methods
A. True
B. False
Answer:
False
Explanation:
The reason is that it should be the opposite. The class's instance variables should be private, and its methods should be private. In that way, only these methods can access to the private variables. For example, you have a class named Person and a variable called ssn (social security number). It is better to make this ssn variable private (It is actually a private information for a person) so that it cannot be read or modified outside of your class.

A bug has resulted in your program executing an infinite loop. What key can be pressed in conjunction with the C or Break (Pause) key to escape the loop______________.
Answer:
The CTRL key is pressed
Answer:
The Ctrl key.
Explanation:
An infinite loop, sometimes called an endless loop, occurs when a program or a portion of a program is running endlessly because no termination condition has been met or set. This may sometimes cause the system to freeze. To manually break out of this loop, a key combination of CTRL and C (CTRL + C) or Break will forcefully end the loop.
Don't forget that a loop is portion of a program that executes repeatedly until a certain condition has been met. So, ordinarily a loop is supposed to end. When it doesn't, then it is infinite.

Which of the following statements is incorrect? Group of answer choices
a.Printer resolution is measured in dpi (dots per inch).
b.Printer output is often called hard copy.
c.Memory within a printer is used to store printing instructions and documents waiting to be printed.
d.Printer speed is measured in the number of words printed per minute.
Answer:
d. printer speed is measured in the number of words printed per minute
Explanation:
a. Printer resolution is measured in dots per inch. So a. is true. Dots per inch means number of ink dots that are printed on the paper by a printer. Higher resolution means better image that is printed.
b. Hard copy also called a print out is the information in the computer which is printed on the paper by a printer. So b. is also true.
c. A printer has memory which is used to store information about the print jobs, print logs, scans. Print jobs are basically the documents which are to be printed these jobs are removed from memory after the printing task is done. So c is also true.
d. Printer speed is measured in pages printer per minute instead of number of words printed per minutes so option d. is incorrect. For example a laser printer can print up to 20 pages of text per minute.
Write a loop that reads positive integers from console input, printing out those values that are even, separating them with spaces, and that terminates when it reads an integer that is not positive.
To read positive integers from console input and print out the even values, you can use a while loop.
To read positive integers from console input and print out the even values, you can use a while loop.
Here's an example:
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int num;
while(true) {
num = input.nextInt();
if(num <= 0)
break;
if(num % 2 == 0)
System.out.print(num + " ");
}
}
}
In this code, we use a Scanner to read the input from the console.
The loop continues until a non-positive integer is entered.
If the entered number is even, it is printed out using System.out.print().
In most modern implementations of the JVM, bytecode is Select one: a. input to the Java compiler b. ready to be executed by a Windows system c. output from the Java interpreter d. input to the JIT (just-in-time) compiler
Answer:
Option d is the correct answer to the above question.
Explanation:
Java is a programming language that gives the features to write the program in one platform and execute it on multiple platforms. The machine code is not given features like this. So for this, the java derived a class file which is then converted file of the java program which is also called the byte code. This code can be transferred on multiple machines and then excite after get converted into machine code. So to convert the byte code into machine code the java needs a JIT compiler which takes inputs as byte code and gives the output as machine code.
The above question asks that which take input as byte code then the answer is JIT which is defined as above and it is stated from option d. hence option d is the correct answer. while the other is not because--
Option 'a' states about the java compiler which gives the output as byte code.Option b states about the window system which is not the correct option.Option c states that it is the output of the interpreter but the interpreter gives the output as machine code in java language.
