The error is here:
...
Age=(int)System.in.read(); // you put 10
System.out.println("Age is="+Age); // Age is 49
...
You get the ascii code of character instead of the number.
http://en.wikipedia.org/wiki/ASCII#ASCII_control_characters
You must to change the code.
for example like this:
http://www.java2s.com/Code/Java/File-Input-Output/UsingBufferedReadertoreadinputnumberfromuser.htm
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class Main {
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String input = reader.readLine();
double number = Double.parseDouble(input);
System.out.println(input + ":" + Math.sqrt(number));
reader.close();
}
}
or in another way.

Hi Elvis ,
Your Employment class should look like this :
import java.util.Scanner;
public class Employment {
public static void main(String[] args) throws Exception {
Employee[] Worker = new Employee[5];
int Age;
int Number;
double Salary;
int x;
Scanner input = new Scanner(System.in);
System.out.println("This is for five workers in my company" + "\n");
for (x = 0; x < 5; x++) {
Worker[x] = new Employee();
System.out.println("\nWorker" + (x + 1) + "\n");
System.out.println("Enter your age:");
Age = input.nextInt();
Worker[x].setEmpAge(Age);
System.out.println("Worker's Number:");
Number = input.nextInt();
Worker[x].setEmpNum(Number);
System.out.println("Worker's Salary:");
Salary = input.nextDouble();
Worker[x].setEmpSalary(Salary);
}
System.out.println("--------------------------------------------------------------------");
for (x = 0; x < 5; x++) {
System.out.println("\n worker :" + (x + 1) + "\n");
System.out.println("Age:" + Worker[x].getEmpAge() + "\n Number:"
+ Worker[x].getEmpNum() + "\n Salary:"
+ Worker[x].getEmpSalary());
}
}
}
and your Employee class like this :
public class Employee {
private int EmpNum;
private double EmpSalary;
private int EmpAge;
public Employee(){
}
public Employee(int num, double sal, int age) {
this.EmpNum = num;
this.EmpSalary = sal;
this.EmpAge = age;
}
public int getEmpNum() {
return EmpNum;
}
public void setEmpNum(int empNum) {
EmpNum = empNum;
}
public double getEmpSalary() {
return EmpSalary;
}
public void setEmpSalary(double empSalary) {
EmpSalary = empSalary;
}
public int getEmpAge() {
return EmpAge;
}
public void setEmpAge(int empAge) {
EmpAge = empAge;
}
}
Thanks,
Ashok A V
