- Java Certification
Sun's certification programs in Java technology are well recognized in the developers' community, global program focusing on different job roles in software application development and enterprise architecture. Due to focus on the technology globally, these certifications are portable from one company to another.
- Continue Statement
The continue statement occurs only inside the iterator statements like while, do or for statements. The continue statement skips the current iteration (for while or a do-while loop).
- Comparable Interface
While writing the object-oriented programs, comparison of two instances of the same class is often required. Once instances are comparable, we can sort them in any order. Comparable interface is defined in java.lang package and is used to define the natural sort order of a class. While the interface java.lang.Comparator defines an auxiliary sort order for a class.
- Java Coding
Coding conventions are the rules that a programmer should govern while develop a program so that their source code can be read and maintain easily. Coding conventions can only be applied to human maintainers and peer reviewers of a software project. Conventions set of rules are kept in a document so that an entire team or company can follow.
- Class path
The Classpath is an argument that is path through the command line. Classpath can also be though an environment variable. Classpath specify the location of the user defined class and the packages in a Java program for the Java Virtual Machine. Setting the class path is mandatory to run a java application. Class path in java can set by using different techniques. Here are the some techniques that can be used to set the class path.
- Byte Code
Bytecode is a term that denotes a form of intermediate code, a binary representation of an executable program designed to be executed by an interpreter or virtual machine rather than by hardware.
- JSP custom tags
JSP custom tags are the user-defined following a special XML syntax to which JavaBean tags (useBean getProperty and setProperty) uses.
- Java for C Developers
Some times ago, many people believed that Java was slower than C because Java had to run through a virtual machine.
AppletContext is an interface that is defined in the java.applet package. It is used by an applet to obtain information from the applet's environment through its methods.
- JNDI Context
Like JDBC (Java Database Connectivity), JNDI is not a service, but a set of interfaces that allows applications to access many different directory service providers using a standardized API. The deployed enterprise beans in EJB have an environment-naming context that can be accessed using the JNDI API.
- Thread Context
The Thread Context is required by the current thread from the group of threads to execute. In java this is achieved through the ThreadContext class. ThreadContext are class loaders.
- Case Java Keyword
The java keyword "case" is used to label each branch in the switch statement in java program.
- Callback Methods
The java keyword "case" is used to label each branch in the switch statement in java program. In other word Case is a java keyword that will be defines group of statements that will begin executing in case a value specified matches value that defined through a preceding switch keyword.
- Casting (Type Conversion)
It is sometimes necessary to convert a data item of one type to another type. Conversion of data from one type to another type is known as type casting. In java one object reference can be type cast into another object reference.
