Employee e1 = new Employee(); Employee e2 = new Employee(); // e1 and e2 refer to two independent Employee objects on the heap Employee e3 = e1; // e1 and e3 refer to the *same* Employee object e3 = e2; // Now e2 and e3 refer to the same Employee object e1 = null; // e1 no longer refers to any object.Additionally, there are no references // left to the Employee object previously referred to by e1.That "orphaned" // object is now eligible for garbage collection.public static void print(Employee e) public void print() public double sqrt(double n) public int max(int x, int y) public synchronized add(Employee e) throws Duplicate Entry Exception public int read() throws IOException public void println(Object o) protected void finalize() throws Throwable public native void write(byte buffer, int offset, int length) throws IOException public boolean equals(Object o) private void process(My Object o) void run() is part of the Employee class, and this is also stored on the heap, where it is shared by all objects of that class.Static fields that are not protected (which we will soon learn how to do) are almost like global variables — accessible to anyone.Here is an example to illustrate this: the goal of the code below is to print a table of values for 2.A common application of loops is to conduct a systematic search through a range of values looking for a value that satisfies some special condition.When writing a while loop you have to take care to ensure that the statements in the body will allow you to eventually reach a state where the loop test evaluates to false.If not, your program will stay stuck in the loop forever.
If the test evaluates to true, execution enters the body of the loop and the statements inside the pair of curly braces gets executed.An example of an application where this is useful is the problem of finding divisors for an integer.To test whether an integer d divides evenly into another integer n we can use this logic: A common application that while loops are useful for is adding up lists of numbers. On each iteration of the loop we compute the next term to be added to the sum, add it to the running total, and then increment the counter.Those of you who have had Math 150 may know that in the limit as N gets very large this sum converges to e = 2.71828182846...It is easy to see that if the loop counter for this sum runs from n = 1 up to n = N, the term we need to add to the running total when the counter is n is 1/n! The problem is that we have no easy way to compute n! The solution to this difficulty is to reuse the strategy we used with powers earlier. and we have that result stored in a variable named Note that the logic here is somewhat touchy and difficult to get just right.
