Access specifiers in java

Access specifiers in java : Access specifiers in java classified into four types for the members. Access specifiers place a very important  role in real time java applications. While developing the application we are defined the members which are  visible outside of the class and which should not visible out side of the package. Suppose in some scenarios  we strictly  hide some of the members which are only visible in side the class and the members which should  not visible any of the...

Java File Input Stream Example

Java File Input Stream Example We can read the files content by using File Input Stream also. File Input Stream  reads the stream of raw bytes. File Input Stream reads the data by using the read() method. File input Stream Example: import java.io.File; import java.io.FileInputStream; import java.io.IOException; //Read the file content using File InputStream. public class FileInputStreamExample { public static void main(String[] args) { FileInputStream fis = null;//<i>File Input Stream</i>...

Java Constructor Example

Java Constructor Example In java the Objects are created by using the constructor. Once we define a class in the java application, automatically the java compiler provides the default constructor. We can define parameterized constructors also depends on our requirement. Example :  Test test = new Test();  class Test{  } In class Test we haven't defined any constructor, here the java compiler provides the constructor. //default constructor in class Test class Test{   Test(){  } } Constructor name must be same as...

Java String

Java String String class is available under the package java.lang.String. String class is very important class, we almost use most of the places while developing the applications. We no need to import this class in our code, automatically this class is available. String is final class, so the string object can not be modify. String class is immutable object, that means its contents can not be editable. There are lot of methods are there to perform string operations like indexOf, concat,charAt...etc We can create string objects in number...

Java static import

java import static Static import in java is the feature which is available in Java 1.5. This is the best feature if we want to use in some real time scenarios. Before java 1.5 if we want to use the static members in another classes/packages we are using the Classname.MemberName, For Example ClassA.Method(); But With this static import feature, we just define the classname/members starting with import static pkg.class; import static pkg.class.memberNames; In the code we can directly use the static members, if we write static import. But...

Linked HashSet Example

LinkedHashSet Example : LinkedHashSet is the class which is available in java.util package. The main advantage of LinkedHashSet is, it preserves the order of the elements. I mean while iterating the LinkedHashSet  the elements are retrieve in the same order how we insert into it. LinkedHashSet implements the Set interface, it allows the Null values and allows unique elements. LinkedHashSet  has lot of methods which are very much useful.
