There's always a time to write code that needs to be ctrl+c,ctrl+v, and in Eclipse if you need to quickly copy a line up and down a line of code, there's a handy shortcut key to use. Place the cursor on a line, press and hold the Ctrl+alt+down, you can quickly copy a row below, press and hold Ctrl+alt+up, that is, you can quickly copy a row on it.Here's one thing to note: Intel's display has a ctrl+alt+ arrow key for its display direction, and its response priority is higher.

Use GDB to debug a running process or analyze a core dump file. See my written "several debugging methods that should be known in GDB" Learn to view information in the/proc directory. This is a running statistic and information for the entire operating system recorded by the Linux kernel runtime, such as:/proc/cpuinfo,/PROC/XXX/CWD,/proc/xxx/exe,/proc/xxx/fd/,/proc/xxx/smaps.

When using eclipse, finding replacements may be a tool we often use, but most of them simply look for replacements for simple word text (such as finding replacement warnings), but in complex situations, most people may manually change.For example:/* */Public class configuration/* */{/*/ Private listWhen we encounter the above code, we can easily replace the "/* * * * * * * * * * * * * * * *, but cannot replace the comment like"/* 41 * * ".In fact, Eclipse's find-and-replace tool supports r

You often use Print statements when debugging, and when you need to add a description string that is confused with the value that needs to be printed, you need to write the string such as "the string here" and then enter the value of the variable. It would be more troublesome to go in this way. Here is a method that can greatly improve the efficiency.Step one: Assume that you need to print the value of temp, first enter the full print string:Step Two: Select temp, press and hold the CTRL+1 key:S
