Program:

import java.util.Scanner;

import java.io.*;

class Main {

public static void main(String[] args) {

try{

Scanner sc = new Scanner(System.in); // Scanner class declaration

/* variable declaration*/

char[] name=new char[100];

char[] occupation=new char[100];

char[] hometown=new char[100];

char[] gender=new char[100];

int age,service;

System.out.print("Name: ");

name = sc.nextLine().toCharArray(); // Accept name from user

String str = new String(name); // Convert to string

for (int i = 0; i < str.length(); i++){ // Loop to check existance of the numbers

if (Character.isDigit(str.charAt(i)) == true){ // check each character existance of the number

System.out.println("Please enter character for Name!!");

System.exit(0); // exit from the program

}

}

System.out.print("Occupation: ");

occupation = sc.nextLine().toCharArray(); // Accept occupation from user

String str1 = new String(occupation); // Convert to string

for (int i = 0; i < str1.length(); i++){// Loop to check existance of the numbers

if (Character.isDigit(str1.charAt(i)) == true){ // check each character existance of the number

System.out.println("Please enter character for Occupation!!");

System.exit(0); // exit from the program

}

}

System.out.print("Age: ");

age = Integer.parseInt(sc.next()); // Accept age from user

sc.nextLine(); // Accept enter

System.out.print("Hometown: ");

hometown = sc.nextLine().toCharArray(); // Accept hometown from user

String str2 = new String(hometown); // Convert to string

for (int i = 0; i < str2.length(); i++){// Loop to check existance of the numbers

if (Character.isDigit(str2.charAt(i)) == true){ // check each character existance of the number

System.out.println("Please enter character for Hometown!!");

System.exit(0); // exit from the program

}

}

System.out.print("Years of Service: ");

service = Integer.parseInt(sc.next()); // Accept service from user

sc.nextLine(); // Accept enter

System.out.print("Gender: ");

gender = sc.nextLine().toCharArray(); // Accept gender from user

String str3 = new String(gender); // Convert to string

for (int i = 0; i < str3.length(); i++){// Loop to check existance of the numbers

if (Character.isDigit(str3.charAt(i)) == true){ // check each character existance of the number

System.out.println("Please enter character for gender!!");

System.exit(0); // exit from the program

}

}

System.out.println("\n\nName: "+str+"\nOccupation: "+str1+"\nAge: "+age+"\nHometown: "+"\nYears of Service: "+str2+"\nGender: "+str3); // Output the details

}

catch(NumberFormatException e){ // Catch if the input is a character instead of a number

   System.out.println("Please enter Number!!");

}

}

}

Output:
