Explanation:
According to the situation mentioned in the question about the model that can make the multi threaded execution faster as compared with the single threaded counterparts programs because multi-threaded programs have the capability to execute simultaneously in multiple processes.
In this type of system ,the blocking system cannot block the complete execution because kernel thread is present for every user thread .So, if one kernel thread gets blocked , others will still keep running .
Whereas, for uni-processor system , the program has to wait for the input -output operation completion for most of the time.Thus, multi-threaded program can execute faster than uni-processor.
public boolean equals(string s)
This statement is the Java Programming in which equals() method compares the original substance of the string
<h2>Answer:</h2>
The correct options are
- Bare metal and hosted
- Memory and operating system based Virtual and physicality
<h2>Explanation:</h2>
There are two types of hypervisors:
Type 1 hypervisor are those hypervisors that run directly on the system hardware such as a “bare metal” embedded hypervisor,
Similarly
Type 2 hypervisor is the kind of hypervisors that runs on a host operating system that provides virtualization services, such as I/O device support and memory management.
Answer:
red
Explanation:
public class CarTest {
public static void main(String[] argvs) {
//below line will create an object of CarTest class Object
CarTest carTest = new CarTest();
//This will call runDemo method
carTest.runDemo();
}
public void runDemo() {
//Below line will create an object of Car class with color blue and 4 wheel
Car c = new Car("blue", 4);
//Bellow Line will change the color from blue to red, see the logic writteen in chnageColor method definition
changeColor(c, "red");
//Below line will print the color as red
System.out.println(c.getColor());
}
public void changeColor(Car car, String newColor) {
//This line will set the color as passed color in the car object
car.setColor(newColor);
}
}
Answer:
b. adds to Iterator the ability to move backwards in the collection
Explanation:
In Java programming, the ListIterator interface adds to Iterator the ability to be bidirectional i.e move backwards and forward in the collection and it is a sub-interface of the Iterator interface.
The ListIterator interface makes it possible to modify any list during iteration and determine its position in the list.
