About SCJP

Since Sun Microsystems (has been incorporated into Oracle in 2009) announced Java technique resolution in 1995, Java has become required technique of important project of system development in industry. Thus, no matter what your future occupation is, e.g. programmer, web developer, system analyzer or J2EE system constructer, you have to fully understand and master Java-based system development technique, which is certified by SCJP. In Java certification system, you must earn SCJP certification first before preparing other advanced certificates, e.g. SCWCD, SCJD and SWBCD because SCJP is equivalent to the proof of Java basis.

Certificate advantage

• International: Linux and Java are both most common technique around global industries so you wouldn’t be worried about job application.
• Priority: the prior recruited condition of 42% IT-related employments depends on whether you earn related certification.
• High salary: the annual income of Java programmer is over 10-30% more than the one of other engineers.
• In addition to the reference of increasing salary, it’s also the important proof of further education, recommendation, studying aboard and emigrant.

Why Java certificate so hot

Java is a revolutionary programming language developed by Sun Microsystems. The other common languages, e.g. C++, Fortran, Pascal and etc., usually needs to change their compiling version according to different platforms. So it results in complexity of software development for information employee in different platforms. However, the appearance of Java modifies traditional compiling method and its cross-platform feature also makes Java program become the most extensive application technique nowadays.

Because of insufficiency of domestic Java talents, the average income of Java professional is much higher. Java possesses rapid, secure and efficient development in immediately promoting your job efficiency. It not only possesses object-oriented and cross-platform feature but owns simplicity, portability, multithread and security. Compared other object-oriented languages, IT employees with programming basis can be easily familiar with Java. In addition, Java has much extensive application in smart card, mobile phone and commerce application system. Many Java users also regard it as object-oriented development tool as well as cross-platform runtime architecture whose element and service can be repeatedly used in database integration.

According to a latest report from Gartner market research company in US, even though IT industry is now encountering the latest depression, the urgent demand of Java technique and related talents is still market tendency right now. This repot says the biggest problem is insufficiency of senior Java professional. Thus, although most companies are now reducing their staffs, they are still desirous of Java talents in the cases of commissioned project.

Java advantage

• Program is easily compiled; long term discipline is no necessary.
• Object-oriented programming that emphasizes on data interface.
• Java has a thorough and distributed library that can easily accords with TCP/IP protocol, e.g. HTT and FTP.
• Java-based application has stability and multiple execution features.
• Java has several phases of interlocking protection in preventing virus intrusion.
• Java compiler will produce an architecture neutral object file format that makes compiling code executes in many processors.
• Java owns portability feature per se.
• Java decompiler can directly execute Java byte codes on any machines so that it can save time to connect with application.
• Java byte code can be rapidly transformed to machine code and such efficiency has no difference to C or C++.
• Java possesses multi thread feature in helping interaction and response ability and instant execution.
• Java is more dynamic than C or C++; it won’t need to be recompiled because of library update.
