Thread: About instance variables in java

Hi I am new in programming world. Currently I am learning JAVA programming language..I have problem with instance variables in java. How can I find 3 instance variables that they have different type and everyone has two methods?If you are having any suggestions then reply me. It can helpful to me.

Try to understand following code. It will solve your problem.

Code:

public class Example
{
int temp;
Example()
{
temp++;
}
public static void main(String[] args){
Example e = new Example();
System.out.println("No. of instances for e : " + e.temp);
Example e2 = new Example();
System.out.println("No. of instances for e : " + e.temp);
System.out.println("No. of instances for e2 : " + e2.temp);
Example e3 = new Example();
System.out.println("No. of instances for e : " + e.temp);
System.out.println("No. of instances for e2 : " + e2.temp);
System.out.println("No. of instances for e3 : " + e3.temp);

}
