Java for COBOL Programmers Training Course

Duration: 5 days
Course code: SS-JAV-013

  • Application Developers
  • System Designers

Experience with at least one structured programming language


The Java for COBOL Programmers training course is specially designed for COBOL programmers seeking to design and develop applications using the Java Standard Edition (JSE). Based on SciSpike's well-received training methodologies, the course provides for a rapid and efficient transition to object-oriented software development using JSE. The attendees are expected to be familiar with COBOL or some other structured programming language. Experience with object orientation would be helpful but is not required.

The Java for COBOL Programmers training course covers topics in object-orientation, the basics of programming using Java, including syntax, compilation, packaging and deployment. The JSE class library and architecture are also covered as well as multi-threaded programming in Java. Other topics covered include concepts in "Interface based design for de-coupled and concurrent development". The Java class libraries covered include: Java utilities, input and output (I/O), web based client development using Java "Applets", a brief introduction to graphical user interfaces development using the Java Swing library, and an introduction to the Java Database Connectivity (JDBC). Where applicable, all the concepts will be conveyed in a way such that COBOL programmers can relate to their familiar COBOL counterparts.

The Java for COBOL Programmers training course consists of a large number of fully worked out example code illustrating various concepts introduced during the course. The concepts are further reinforced through the use of well-crafted exercises at appropriate points throughout the course.


SciSpike's goal is to transfer as much knowledge as possible from the classroom to the workplace. This course has been carefully designed to ease COBOL developers into Object-oriented design using Java with the use of lots of exercises, labs, and sample code. At the end of this course, students should:

  • Have a firm understanding of the Java architecture
  • Identify basic concepts of Object Oriented design
  • Be able to map concepts from COBOL to Java
  • Be able to implement Object Oriented based applications
  • Be able to design and implement effective Java programs
  • Be able to effectively use the IDE (RAD, Eclipse etc.)
  • Be able to build multi-threaded programs using Java
  • Have the necessary foundation to pursue advanced topics in Java
