    Default Having Difficulties With a Multi Thread Code... Help?

    There is an issue with part of my program, I get two errors.. And I have no idea how to fix it. Here is what I have for the code:

    class Customer{
    private String name;
    private int age;
    public Customer(String n, int a)throws CreateException{
    if(0<a<125){
    Name=n;
    Age=a;
    throw new CreateException(&#8220; Age limit is 0 to 125 &#8221;);
    }
     
    }
     
    public void print(){
    System.out.println(" The Name:" +Name);
    System.out.println(" The Age:" +Age);
    }
    }

    public class CustomerDemo{
    public static void main(String args[]){
    Customer cust[]=new Customer[2];
    for(int i=0;i<2;i++){
    try{
    c[0]=new Customer(&#8220;Ram&#8221;,60);
    c[0].print();
    }catch(CreateException e){
    System.out.println(&#8220; Complete &#8221;);
    System.out.println(e.getMessage());
    }
    }
    }
    }

    Hi... I think you have to work hard on your basics..

    1) if(0<a<125) condition is wrong. It could be if((0<a)&&(a<125))
    2) Your declared variables are
    private String name;
    private int age;
    And you are using
    Name=n;
    Age=a;
    This is again basic, declared name of variable are different then assigned one.

    3) In customer demo class
    c[0]=new Customer(“Ram”,60);
    c[0].print();
    Where is the array of c, i think it should be cust.
    ---------------------------------------------------
    package com.java.main;
     
    class Customer {
    	private String name;
    	private int age;
     
    	public Customer(String n, int a) throws Exception {
    		if ((0 < a) && (a < 125)) {
    			name = n;
    			age = a;
    			throw new Exception("Age limit is 0 to 125");
    		}
     
    	}
     
    	public void print() {
    		System.out.println(" The Name:" + name);
    		System.out.println(" The Age:" + age);
    	}
    }
    ----------------------------------------------------
    package com.java.main;
     
    public class CustomerDemo {
    	public static void main(String args[]) {
    		Customer cust[] = new Customer[2];
    		for (int i = 0; i < 2; i++) {
    			try {
    				cust[0] = new Customer("Ram", 60);
    				cust[0].print();
    			} catch (Exception e) {
    				System.out.println("Complete");
    				System.out.println(e.getMessage());
    			}
    		}
    	}
    }
