You can also use an enhanced for statement, which lets you retrieve the elements without bothering with indexes or the get method:. for (String s: nums) System.out.println(s); Here, each String element in the nums array list is printed to the console. To determine the index number of a particular object in an array list when you have a reference to the object, use the indexOf method.
Java program without main We need a main method for executing a program. But YES we can write a program without using main() method. TRICK 1 of 2 :: while writing applets in java we don't use main.
Java class objects exhibit the properties and behaviors defined by its class. A class can contain fields and methods to describe the behavior of an object.

JAMA is based on a single matrix class within a strictly object-oriented framework. Jampack uses a more open approach that lends itself to extension by the user. As it turns out, for the casual user the packages differ principally in the syntax of the matrix operations. We hope you will take the time to look at Jampack along with JAMA. There is much to be learned from both packages.
Thus, the fully qualified name of the class is: java.util.Arrays I will cover a few of the methods found in this class in the following sections. Remember, in order to use java.util.Arrays in your Java classes you must import it. Here is how importing java.util.Arrays could look in a Java class of your own.
