5. Share some debugging tips in Eclipse
Variables we watch and program breakpoints we add will not be automatically deleted by Eclipse. Unless we manually delete them, they will remain in the purple box. These values will slow down the Eclipse development tool, if there are too many bugs in Eclipse, it is likely to cause Eclipse to crash, making development very painful, we recommend that you manually clear all the program breakpoints and watched variables added in the purple box during each Debug and debugging. You only need to add the breakpoints required for this debugging, in this way, Eclipse will not be crashed by these slow processes.
