String in While loop

[nebulared]

I am trying to create a while loop that reads the users input which is string. If the string doesnt match it will ask the user again to give the input. When i tired to create while loop it doesnt exit even though the string match. here is something i did.

System.out.println("What surface do you want?");
Scanner object = new Scanner(System.in);//creating the scanner object
String x = object.next();//scans from keyboard

while((!x.equalsIgnoreCase("t")) || (!x.equalsIgnoreCase("x")) ||(!x.equalsIgnoreCase("g")))
{
System.out.println("What surface do you want?");
x = object.next();
}

Use a Venn diagram and you'll see that the condition in your while loop is always true and so the loop will never end. Or use logic: At least two out of the three conditions will always be true, and since you're "or-ing" the three conditions, the whole statement will always be true.

Perhaps "or" isn't the answer (hint).

1. Use code tags.
2. Use && instead of ||. You have problem with your logic statement.

i kinda figure out how to do. Now it looks like this
while(!((x.equalsIgnoreCase("t")) || (x.equalsIgnoreCase("x")) ||(x.equalsIgnoreCase("g"))))

how ever new problem showed up. It did what i wanted to do but i want to ask the user if they want to ask the new object and repeat the process. like if the x equals the users in put it does the calculation and ask if they want to do new calculation. How to use while loop on this.

current code


import java.util.Scanner;

public class AreaDriver
{

public static void main(String[] args)
{
System.out.print("Choose a solid surface: ");
Scanner object = new Scanner(System.in);//creating the scanner object
String x = object.next();//scans from keyboard

while(!((x.equalsIgnoreCase("sphere")) || (x.equalsIgnoreCase("box")) ||(x.equalsIgnoreCase("cone")) || (x.equalsIgnoreCase("n"))))
{
System.out.print("Choose a solid surface: ");
x = object.next();
}



if(x.equalsIgnoreCase("sphere"))
{
does something


}
else if(x.equalsIgnoreCase("box"))
{
does something
}

else if (x.equalsIgnoreCase("cone"))
{
does something
}

}

}


i want user to ask here if they want to do it again. Whether is new or repeat. the whole processs.
