I recently typed out this java program to accept ten areas and their pin-codes and then search to find a particular area and print out it’s pin-code. Here’s the code from the program :
import java.util.Scanner;
public class Sal {
public static void main (String args []){
Scanner s=new Scanner(System.in);
System.out.println("Enter 10 areas and their pincodes");
String area[]=new String [10];
int pincode[]=new int [10];
String search;
int chk=0;
int p=0;
for (int i=0;i<=9;i++){
area[i]=s.nextLine();
pincode[i]=s.nextInt();
}
System.out.println("Enter Search");
search=s.nextLine();
for (int j=0;j<=9;j++){
if(search==area[j]){
chk=1;
j=p;
break;
}
}
if(chk==1){
System.out.println("Search Found "+"Pincode : "+pincode[p] );
} else {
System.out.println("Search not Found");
}
}
}
And after entering two areas I get this ERROR:
Exception in thread "main" java.util.InputMismatchException
at java.util.Scanner.throwFor(Unknown Source)
at java.util.Scanner.next(Unknown Source)
at java.util.Scanner.nextInt(Unknown Source)
at java.util.Scanner.nextInt(Unknown Source)
at Sal.main(Sal.java:14)
Can someone please tell me what I’m doing wrong! :/ Any help is appreciated.
First of all, remember to indent your code for readability.
Concept 1.
Concept 2.
// compare Strings using compareTo method (which returns 0 if equal
Rest of your code and concepts are correct 🙂
