If you just want to print the results to the TXT in reference 1 floor, if you want to print to the console display information in the TXT, can use the CMD way to run a Java program, and then the content of the print is redirected to the new TXT file, 1. To compile the first class javac class name. Java, generates a class file, (2) execute Java class file name (don't add the suffix) & gt; Test. TXT, such console information content will be printed to the test. The TXT file
