Enter the debug mode: 1. Set the breakpoint. 2. Start the debug mode of the servers. 3. Run the program. When a breakpoint occurs in the background, go to the debug debugging status ============================ scope function shortcut
F7 is returned in one global step.
Skip F6 in one global step
Global One-Step Jump to F5
Global One-Step Jump-in and select Ctrl + F5
Global debugging last started F11
Continue F8 globally
Shift + F5 in one step using filters globally
Globally Add/remove breakpoints Ctrl + Shift + B
Global display Ctrl + d
Global run last started Ctrl + F11
Run Ctrl + R globally
Globally execute Ctrl + u =============================1. step into (also F5) Jump
2. Skip step over (also F6)
3. Step return (also F7) after executing the current method, return jumps out of this method
4. Step filter: gradually filter and execute until unfiltered locations or breakpoints are encountered (set filter: window-preferences-Java-debug-step filtering)
5. Resume re-runs debug until it encounters a breakpoint.
For example, if two breakpoints A and B are found to be useless during the debug process, and the breakpoint is removed, running resume will skip a and directly reach the B breakpoint.
6. hit count: Set the execution times to be appropriate for the for loop in the Program (Set breakpoint view-right-click hit count)
7. Inspect check operation. Execute an expression to display the execution Value
8. watch monitors changes to objects, methods, or variables in real time. we often say that the breakpoint refers to line breakpoints. In addition to line breakpoints, there are other breakpoint types: field (watchpoint) breakpoint, method breakpoint, exception breakpoint.
10. Field breakpoint is also called watchpoint. It is temporarily suspended when the member variables are read or modified.
11. Run-method breakpoint)
12. When exception breakpoint is added to catch execption (To be continued ...)
Breakpoint attributes:
1. How many times of hit count execution will be suspended for Loop
2. When enable condition meets your input conditions (if it is true or changed), it will be suspended temporarily.
3. This thread is temporarily suspended when suspend thread is multithreading.
4. The suspend VM temporarily suspends the VM. the variables in the variables view can change the variable value. In the variables view, right-click the variable and choose change value for quick debugging.
14. after some code is modified in the debug process, --> Save & build --> resume temporarily at the breakpoint 15. resume when debug runs out of an exception, run resume and start debugging again from the breakpoint.
16. If a row has many methods,
When you press F5 for the first time, you can jump into the first method of this line. F6 performs step-by-step debugging and F7 jumps out of this method.
When you press F5 for the second time, you can jump into the second method of this line. F6 performs step-by-step debugging and F7 jumps out of this method.
And so on. To enter the first method of this line, press F5 and f7.
