because you have to give unique names to all objects

I tried the same thing actually: // for (int i = 1; i <= 5; i++) { // Zerg z+i = new Zerg(); // z+i.name = "Zerg" + i; } I couldn't quite get the syntax right to resolve the "z+I" or it was failing in anycase. Did you continue with your Java journey in the end?

Well you can certainly do like that, but in our course we are yet to be introduced to LOOP concepts. So using what ever we learnt upto that point, I didn't use Loops and did it in a primitive way.

How are you write table 1 to 10 by printing one by one number . I use simple nested loop to print that . If you don't know how to use please follow this link Looping concept

for(int i=1;i<=10;i++) { for(int j=i,k=0;k <=10;j++,k++) { System.out.print(i * j +" "); } System.out.println(); } // I didn't see your solution. You can see my solution in nested loops here. Thanks!!!

why did you tell me that i can't use loop concept here?

the loop is creating the same object over and over again

according to my knowledge, you have to create a class for Zerg, then zergi will be the object of that class. example i can create a class of Car, then to create an object for the Car class, i'd say Car honda = new Car(); and creating an object after a loop is bad programing practice which will generate an error unless it is possible in an advanced section.

public class Uy{

public static void main(String [] args) {
 char[ ]  hi= {'a','b','c','d','e'};
for(int i =0; i<5; i++)
 {
   Raj raji = new Raj();
   raji.name=hi[i];

     System.out.println(raji.name);
 }
}
public static class Raj
{  char name;
}
}

you did exactly what i pointed out in my reply, but to reiterate, i've never seen a code like that before because you did not need a class for this code, it is a waste of memory, plus as someone starting out with java i don't see the point to it. but to each their own

It's cool sure but unnecessary. and I agree, added memory is a concern.
