Error handling in JAVA - Check correct input type

Question

Not sure where i'm going wrong, please help. Trying to check if the user has only entered an integer. Error showing strInpit cannot be resolved to a variable.

import java.util.Scanner;

public class Salary{ 
  public static void main(String[] args){
    int num = 0;
    String strIntput;
    boolean valid = false;
    

    // setup scanner
    Scanner in = new Scanner(System.in);
    // loop to check for valid input
    while(valid == false){
      //prompt user to enter
      System.out.println("Enter your salary per year");
      // grab input from keyboard
      strInput = in.nextLine();
      // try to convert String to int
      try{
        num = Integer.parseInt(strInput);
        valid = true;
      }
      catch(NumberFormatException e){
        System.out.println("Error - enter an integer value.");
      }
    }
    System.out.println("your salary is " + num);
  }
}

I am voting to close this question because it was caused by a typo, and as such it is unlikely to be of help to future visitors to this site. — andrewJames

you have named the variable as String strIntput;

while declaring it..but you are using strInput everywhere else

so change String strIntput; TO String strInput;

There is another method which you can use: #Scaner.nextInt(); It will get Integer value from console or, in another case, will throw an exception
