Hello all!

I am currently trying to learn some Java, and ran across something.

Let's say I prompt a user to input Yes or No, but I WANT the program to "catch" if they input something else - like a typo, and prompt them to enter Yes/No again.

I know how to do this with positive/negative doubles/Int. (see code snappet below) but how would I do this with strings?

Code: [Select]
{
System.out.print( "\nEnter PAY rate: " );
PayRate = input.nextFloat();
if( PayRate > 0 )
Rate = true;
else
{
System.out.print( "Number must be positive" );
}
}

My starting code for the strings is this:

Code: [Select]
{//Start Case Option Module
System.out.print( "\nWill this case have Edge Casters" );
System.out.print( "\nEnter \"Yes\" or \"No\"" );
CasEdgeAns = input.nextLine();
if (CasEdgeAns.equalsIgnoreCase( "Yes" ))
{//If yes condition start
CasEdge = true;
System.out.print( "\nCase will have edge casters." );
}//If yes condition end

else if (CasEdgeAns.equalsIgnoreCase( "No" ))
{//If no condition start
CasEdge = false;
System.out.print( "\nCase will not have edge casters." );
}//If no condition end

//Something here like
//if (CaseEdgeAns != Yes && CaseEdgeAns != No)
//System.out.print( "\nPlease enter \"Yes\" or \"No\" );


}//End case option module

Ideally, I want it to prompt the user to enter either yes or no, and will not continue until done so (I will probably need a boolean for a do...while statement for that block, I GUESS?).

Any help or hints would be greatly appreciated, thanks!
This whole thing is a big work in progress so I can post the full code if needed. Thanks!Since from the looks of it you will be doing quite a few prompts like this it would make sense to make it a separate method, like so:

Code: [Select]import java.io.InputStream;
import java.io.OutputStream;
import java.util.Scanner;
import java.util.stream.Stream;

public class BoolSelect {

/**
* @param args the command LINE arguments
*/
public STATIC void main(String[] args) {
boolean result = PromptChoice();
System.out.println("Selection was:" + result);
}
public static boolean PromptChoice(){

Scanner s = new Scanner(System.in);
boolean foundresult = false;
while(!foundresult){
System.out.print("Enter your choice (Y/N):");
String sread = s.nextLine();
if(sread.equalsIgnoreCase("Y")) return true;
if(sread.equalsIgnoreCase("N")) return false;
System.out.println("Invalid Choice.");
}
System.out.println();
return false; //this code is hueristically unreachable but the compiler complains...
}

}
Thank you for you help again! Haha you are the best ^.^
