Eclipse saves the console output directly to a text file __eclipse

When running a Java program, the console output too much, or run multiple Java programs at the same time, the output flash past, you can consider the console output, to output to a text file. Without modifying the Java code and introducing a stream so complex, you can directly let eclipse print the output of the console to a text file, as follows:

In Eclipse, select the target's Java file, right-click, select Run->run configurations->common->standard input and output, and select the file you want to save in file, or a new file (for example: C:\a.txt), as shown in the following illustration:


If the A.txt file does not exist, Eclipse automatically creates the log file to save the output.

This eliminates the difficulty of handling the console output.
