input.nextLine();

[Cass29]

Hi everyone hope someopne can help me. I'm writing a code that holds a clients details and I want to check if the right details are displayed. When I prompt the user to enter the new details I'm getting two line diplayed as one. Here is the section of code I have

public void checkDetails()
{

int correct;

Scanner input = new Scanner(System.in);

System.out.println( "Are the Details Displayed Above Correct? (Please Enter 1 for Yes and 2 for No" );
correct = input.nextInt();

System.out.println();

while( correct == 2 )
{
System.out.println("Please Enter Clients Name:");
clientName = input.nextLine();

System.out.println("Please Enter Clients Street Address:");
clientStreet = input.nextLine();

System.out.println("Please Enter Clients Town:");
clientTown = input.nextLine();

System.out.println("Please Enter Clients State:");
clientState = input.nextLine();

System.out.println("Please Enter Clients Budget:");
clientBudget = input.nextInt();

}
}

The problem is that Enter Clients Name and Enter Clients Street
comes out together without a space to enter the name so whatever I enter for name is stored as the stree address.

If you type '2' (for incorrect details) note that you actually type <2> <enter> so two chars are present in the input buffer; the nextInt() method reads the <2>, takes it from the buffer and converts it to an int but it leaves the <enter> in the input buffer (because its not part of an int representation). Next you attempt to read an entire line, that method finds the <enter> character in the input buffer and duly decides that you have typed an empty line and returns.

You have to get rid of that <enter> key in the input buffer; simply read a line by calling the nextLine() method (and discard its return value) before you want to read a client's name.

kind regards,

Hi Cass29 welcome to the forum.

1. Please enter your code between the tags "code", the "#" symbol that appears when you type the text of your post. :D

2. Please avoid using nextInt(); nextDouble(); nextFloat(); etc methods because they do not recognize "enter" as part of what you wrote (since "enter" is not a number). That's a problem because "enter" still remains in buffer and when you try to read another information from the keyboard, it skips this information.
Use nextLine() instead.

Change:

correct = input.nextInt();

for

correct = Integer.parseInt(input.nextLine());

3. You have boolean type value in Java. Try to use it.

                int choice;
		boolean correct;

		Scanner input = new Scanner(System.in);

		System.out.println( "Are the Details Displayed Above Correct? (Please Enter 1 for Yes and 2 for No" );
		choice = Integer.parseInt(input.nextLine());

		correct = (choice == 2);
		System.out.println();

		while( correct )
		{

4. You never change the value of your while condition. That will result in an infinitive loop.

Thanks for the help guys, the code is working perfectly now.
