Answer:

= is used more for define a variable so int Data = 1;

Where == is used to show if something is equal too.

exp of == would be

int Data1 = 1;

int Data2 = 2;

if(Data1 == Data2)

{

System.out.println("Hi")

}

else

System.out.println("Not Equal");

//Output

Not Equal

//Reason was they didnt equal and the boolean was false not true.

Explanation:

Hope this helped!

= is for assignment, == is for comparison.

So x=2 means: assign the value 2 to the variable x.

and

x==2 means: is variable x equal to 2, yes or no?

worty [1.4K]

Answer:

The correct answer would be option B, Track changes.

Explanation:

John's job is to make drafts and print them. Before printing them, he sends the copy to the manager to get it checked for any mistakes. John's manager can give suggestions and edit the document where he thinks he needs to do. So he can use the Track changes feature to give his comments or suggestions as well as to edit the document. He will simple open the document, open the Review tab, and Click on the Track changes or comments icon. Here he can click on the text which he wants to edit, and there will be a pan which will keep track of the changes and mark them with red, so that John knows where he has made the changes or given the suggestions.

S_A_V [24]

Answer:

// program in C++.

#include <bits/stdc++.h>

using namespace std;

int main() {

// variable

int num;

cout<<"Enter the number between 20 and 98: ";

// read number

cin >> num;

while(num<20||num>98)

{

cout<<"Wrong input!!enter number between 20-98 only:";

cin>>num;

}

cout<<"The output is: ";

while(num % 10 != num /10)

{

// print numbers.

cout<<num<<" ";

// update num.

num--;

}

// display the number.

cout<<num<<endl;;

return 0;

}

Explanation:

Read a number from user and assign it to variable "num".Check if entered number is in between 20-98 or not.If input number is less than 20 or greater than 98 then ask again to enter a number between 20-98 until user enter a valid input.Then print the countdown from input number till both the digit of number are same.

Output:

Enter the number between 20 and 98: 99

Wrong input!!enter number between 20-98 only:12

Wrong input!!enter number between 20-98 only:93

The output is: 93 92 91 90 89 88

Enter the number between 20 and 98: 77

The output is: 77

. Write a toString method for this class. The method should return a string containing the base, height and area of the triangle

marta [7]

Answer:

Check the explanation

Explanation:

Circle.java

public class Circle {

private double radius;

public Circle(double r) {

radius = r;

}

public double getArea() {

return Math.PI * radius * radius;

}

public double getRadius() {

return radius;

}

public String toString() {

String str;

str = "Radius: " + radius + "Area: " + getArea();

return str;

}

public boolean equals(Circle c) {

boolean status;

if (c.getRadius() == radius)

status = true;

else

status = false;

return status;

}

public boolean greaterThan(Circle c) {

boolean status;

if (c.getArea() > getArea())

status = true;

else

status = false;

return status;

}

I have created a class also to test this class below is the class: -

MainCircle.java

public class MainCircle {

public static void main(String args[]) {

Circle c = new Circle(2.5);

Circle c1 = new Circle(2.5);

Circle c2 = new Circle(4.5);

System.out.println(c);

System.out.println(c1);

System.out.println(c2);

System.out.println("Is c and c1 equal : "+c.equals(c1));

System.out.println("Is c2 greater than c1 : "+c1.greaterThan(c2));

}

Output: -

Radius: 2.5Area: 19.634954084936208

Radius: 4.5Area: 63.61725123519331

Is c and c1 equal : true

Is c2 greater than c1 : true
