| We developed a set of histograms and other utility classes in this 
              course primarily for educational purposes but they can also be useful 
              for your own analysis work. However, you certainly don't need to 
              develop every Java programming tool yourself. There are lots of 
              class libraries for math, scienee, and other technical areas already 
              developed and many of them are available for free.  The Resources section provides 
              links to various online programs and libraries that support technical 
              program development. In Chapter 
              12: Physics section we described a number of the math and analysis 
              packages available for physics programming. Here we look at a selection 
              of packages that are useful for technical programming in general, 
              especially for charting,  |
