COBOL Programmers Swing with Java

E. Reed Doke, Bill C. Hardgrave, Richard A. Johnson9780521546843, 0521546842

Featuring the development of graphical user interfaces (GUI’s) using the latest in Java swing components, this new edition of Java for the COBOL Programmer (Cambridge, 1999) provides COBOL programmers a clear, easy transition to Java programming by drawing on the numerous similarities between COBOL and Java. The authors introduce the COBOL programmer to the history of Java and object-oriented programming and then delve into the details of the Java syntax, always contrasting them with their parallels in COBOL. A running case study permits the reader to have an overall view of application development with Java. First Edition ISBN (Pb): 0-521-65892-6
