20165339 experiment a familiarity with the Java development environment

Experiment with familiarity with a Java development environment 1

• 1. Using the mkdir 20165339exp1 build directory

• 2. Use mkdir 20165339exp1/bin and mkdir 20165339exp1/src build src and bin directories under 20165339EXP1
  

• 3. vim Hello.java Create a source file using the SRC directory

• 4. Use the javac -d bin src/Hello.java compile source file and place the class file in the Bin directory. Use java -cp ./bin Hello run.
  

Familiarity with the Java Development Environment 2

• Create a new project after installing the idea and configure the JDK to create the class file in the SRC directory
  
• Input code
  
• After setting a breakpoint, click menu "run"->"debug..." Debug Java program.
  
  The value of sum is not 11
  
• The value of sum after one F8 is changed to 11
  
• Set conditional breakpoint, right-click on line 9th, enter i==50
  

Familiarity with the Java development Environment 3
