How to take input as String with spaces in java using scanner

Question

I need to read spaces (present before string and after String) given as input using Scanner Note : if there is no spaces given in input it should not add space in output

Answer 1

I use this function below, to read from all user input format, text inclusive spaces, then parse to specific datatype after.

package practice;
import java.io.*;

public class readInputSample{
   public static void main(String[] args) {
        String strVal = getInput("Enter string value: "); // Direct as string
        Integer intVal = Integer.parseInt(getInput("Enter integer value: "));
        Double dblVal = Double.parseDouble(getInput("Enter double value: "));
        Float fltVal = Float.parseFloat(getInput("Enter float value: "));

        System.out.println("String value: " + strVal);
        System.out.println("Integer value: " + intVal);
        System.out.println("Double value: " + dblVal);
        System.out.println("Float value: " + fltVal);
   }

   // Special Function to read all user input
   private static String getInput(String prompt){
      BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));

      System.out.print(prompt);
      System.out.flush();

      try{
          return stdin.readLine();
      } catch (Exception e){
        return "Error: " + e.getMessage();
      }
    }
}
