Answer:
public class ANot {
public static void main(String[] args) {
int numberOfSides = 20;
boolean isQuadrilateral;
if(numberOfSides==4){
isQuadrilateral = true;
System.out.println("The triangle is quadrilateral");
}
else{
isQuadrilateral=false;
System.out.println("The triangle is not quadrilateral");
}
}
}
Explanation:
- Create and Initilize the int variable numberOfSides (You can also receive this from a user using the scanner class for example).
- create a boolean variable isQuadrilateral
- Use if and else statement to check if numberOfSides ==4 and assign true to isQuadrilateral else assign false
Answer:
its easy
Explanation:
there are are 5 main rules
in binary there are 2 number 0 and 1
0 + 0 = 0
0 + 1 = 1
1+0=1
1+1=0 carry 1
e . g
1 1 1
1 0 1 0 1 0
+ 1 1 0 0 1 0
-------------------------
1 1 1 1 1 0 0
*in bold are the ones that you need to carry.
in decimal there are 10 possible numbers 0- 9
when you do 1 + 9 it becomes 10, this can be done easily, however if you do 1 + 9 in a table like above, you will get 0 for the first column and you will carry 1 to the next column .
in binary is the same idea but using on 2 numbers 1 and 0
e.g
1
1
+ 9
----------
1 0
*in bold are the ones that you need to carry.
hope it helps and good luck in your exam.
It really depends what device you're on.
For example, my wifes laptop shows a lock screen, then it shows a sign in screen.
My laptop shows ONLY the sign in screen.
My old laptop shows a sign in screen with the date and time. So I dunno man
