I'm trying to compare a string but when I have the user input a string it doesn't let them

Question

    System.out.println( "Great! Now select the type of measurement this is so we can convert!");
    System.out.println( "G = Gallons" );
    System.out.println( "I = Inches" );
    System.out.println( "P = Pound" );
    System.out.println( "M = Mile" );
    String userType = input.nextLine();

I enter a number, and then when I should be entering the measurement type (as shown above) it automatically skips to the if statement that is after this. Nothing I've tried has worked. Can anyone help?

Answer 1

You must

input.nextLine();

after your read in number part when you go from reading in a number from scanner to a string

I hope this works and helps you in the future.

Answer 2

Use BufferedReader Class

Try the following code:

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
  System.out.println( "Great! Now select the type of measurement this is so we can convert!");
  System.out.println( "G = Gallons" );
  System.out.println( "I = Inches" );
  System.out.println( "P = Pound" );
  System.out.println( "M = Mile" );
  String userType = br.readLine();

Import required is:

import java.io.*;

You can campare two string by using String functions

Example:

if(String1.equals(String2)){
//Both the strings are equal
}
else{ 
//Both string are not equal
}

You can even use "campareTo" function.
