Further we have to directly connect its output channel to the Java process’ output channel, which works starting with Java 7, using inheritIO(): import java.io. Go to the Java Control Panel / Java / Java Runtime Settings / View / User / Runtime Parameters And add the options to enable debugging. Run IteratorError.java and observe its output. Open IteratorError.java in jGRASP and compile it. How does it work Integrated Development Environment (IDE) comes with three main components a code editor, compiler, and debugger. You can identify and learn to correct this common error through the steps below. To solve this problem, we have to invoke the command line interpreter ( cmd) and tell it to execute a command ( /c cls) which allows invoking builtin commands. Computer Science Computer Science questions and answers A common error in using iterators arises from a misunderstanding of what the next () method actually does. But when the output of the cls command gets redirected, it doesn’t clear the console. When launching a new process via Runtime.exec, the standard output gets redirected to a pipe which the initiating Java process can read. If your application seems to be unresponsive, you can pause the program to analyze where your code is stuck. There is no executable named cls.exe or cls.com in a standard Windows installation that could be invoked via Runtime.exec, as the well-known command cls is builtin to Windows’ command line interpreter. Exercise - jGRASP Debugger The program prints a progress dot every 200 iterations. Pause, resume, restart, or stop the debugger. ![]() This command does not work, for two reasons: Open debugger canvas in new window Variables from the original debug tab can be dragged to this window. Since there are several answers here showing non-working code for Windows, here is a clarification: Runtime.getRuntime().exec("cls")
