Hello fellow Treehousers! I tried to implement a loop on an age requirement and I've been playing around with some code. The issue that even if you user does not meet the requirement of the program, the program still proceeds and the user is not prompted to meet the age requirement again before proceeding. Here is the code. I'm open to any feedback on areas I can also improve. I've add comments in areas I think I need some serious help in. Thank you Treehousers ^_^
package treehouse1;
import java.util.Scanner;
public class TreeHouse1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String ageAsString;
do{
//Do I need this do here?
System.out.printf("How old are you?");
ageAsString = input.nextLine( );
int age = Integer.parseInt(ageAsString);
if ( age <18)
//Is this if doing anything? xD
System.out.printf("Sorry you must be at least 18 to use this program.\n");
}while (false);
// I seem to be using this while wrong, can anyone shed light pls and ty
String firstName;
String adjective;
String noun;
String adverb;
String verb;
//adding a bunch of strings
System.out.printf("What is your name?:");
firstName = input.nextLine( );
System.out.printf("Enter an adjective: ");
adjective = input.nextLine( );
boolean isInvalidWord;
do{
System.out.printf("Enter a noun:");
noun = input.nextLine( );
isInvalidWord = (noun.equalsIgnoreCase("nerd")||
noun.equalsIgnoreCase("dork")||
noun.equalsIgnoreCase("moron"));
if (isInvalidWord) {
System.out.printf("That language is now allowed. Try Again. \n\n");
}
} while (isInvalidWord);
System.out.printf("Enter an adverb: ");
adverb = input.nextLine( );
System.out.printf("Enter a verb ending with -ing ");
verb = input.nextLine( );
System.out.printf("Hello, my name is %s!\n", firstName);
System.out.printf("%s is a %s %s.\n", firstName, adjective,noun);
System.out.printf("%s is always %s %s.\n", firstName, adverb, verb);
}
}

package treehouse1;
import java.util.Scanner;
public class TreeHouse1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String ageAsString;
int age;
do{

ageAsString = input.nextLine( );
age = Integer.parseInt(ageAsString);
if ( age <18)
System.out.printf("Sorry you must be at least 18 to use this program.\n");
}while (age < 18); //bundle of code ends here

if ( age <18)
//Is this if doing anything? xD
System.out.printf("Sorry you must be at least 18 to use this program.\n");
If I am correct you are missing the braces:
if ( age <18) {
System.out.printf("Sorry you must be at least 18 to use this program.\n");
}
