public static void main(String[] args) {

int P; float R; int T ; float SI;
System.out.println("Enter Principal");
Scanner newScan = new Scanner(System.in);
P= newScan.nextInt() ;
System.out.println("Enter Rate");
R=newScan.nextFloat() ;
System.out.println("Enter Time");
T= newScan.nextInt();
System.out.println("You Entered P : " + P );
System.out.println("You Entered R : " + R );
System.out.println("You Entered T : " + T );
System.out.println("Is this correct ? Press Y/N");
String UserInput = newScan.nextLine();
String Y = "Y";
String N = "N";
if(Y == UserInput) {
System.out.println("Continuing");
SI = P * R * T / 100;
System.out.println("The Result is " + SI);
}else if (N == UserInput) {
System.out.println("You Have chosen to quit");
System.out.println("Quiting.....");} else {
System.out.println("You made a wrong choice");}

}
}

This is output
Enter Principal

You Entered P : 45
You Entered R : 4.0
You Entered T : 3
Is this correct ? Press Y/N
You made a wrong choice

Please Help me

Answer 1

Read this, there is your answer.
https://www.geeksforgeeks.org/why-is-scanner-skipping-nextline-after-use-of-other-next-functions/amp/?ref=rp

Because you take numbers with nextInt etc, they don't consume the last line feed from system.in
So UserInput will be an empty string because the first character it finds is actually a line feed.

Solution: before you ask for Y/N insert another nextLine()

Answer 2

SoloLearn courses teach you only very basic stuff, so it won't be enough for Android development, but it's a good start. 😉

Answer 3

Always compare objects (non-primitive types) with the equals() method.

if (N.equals(UserInput))

like that.

Answer 4

It is not waiting for my 2nd input which is going to be held in UserInput variable.

Answer 5

It worked, Thank You So Much buddy

Answer 6

In if condition you should use equals method because it should match the values but not the references
