Jgrasp debugger structure11/9/2023 For example, we'll Step In to the call of drawEgg from our previous example. The most useful of these buttons is Step In, so if you only learn to use one of them, make it that one. Auto Step: When you turn on this button and then press Step Over/In/Out, it will repeatedly perform that action. Resume: Tells the program to continue executing until it is finished, or until another breakpoint is encountered.Run to Cursor: Executes lines until reaching the line where your keyboard cursor is sitting.(If you click this while in your main method, it runs the rest of your entire program.) Step Out: Executes all remaining lines of the method you are currently in, and returns to the place from which it was called.If the current line is a method call, jumps inside that method and pauses at its first line of code. If the current line is a method call, runs that entire method call. From left to right, their behavior is the following: These buttons control the execution of the debugger. Notice that near the top-left corner of jGRASP, there is a new set of buttons. The next line to execute will be highlighted. The program will run until it hits the line of your breakpoint. Once you have set the breakpoint, compile your program (if you haven't already) and then press the ladybug icon to run it in debugging mode. (One good place to set a breakpoint is on the first line inside your main method, so that you can step through the entire program's execution.) To set a breakpoint, move your mouse cursor to the left margin of your file's editor window until the cursor becomes a stop sign, and press the left mouse button. To use it, first you must tell jGRASP where to pause the execution this is called a breakpoint. From there, you can run each line one at a time and see the results. The debugger lets you run your program partially and then stop it. jGRASP interactions pane tutorial video by the jGRASP authors.ACM SIGCSE Bulletin Association for Computing Machinery JGRASP debugger tutorial video by the jGRASP authors Copyright is held by the author/owner(s). Viewer for LinkedBinarySeatchTree jGRASP is supported, in part, by a grant from the National Science Foundation, and it is freely available (). UML class diagram for Tree_Project Figure 3. Stepping through addElement method Figure 1. During this step, the node was moved in animated fashion from the Local Variable Node References area of the viewer into the data structure itself. The dynamic object view of lbst in Figure 3 indicates the state of the instance after the links for the node with element value 11 are set and prior to count being updated. In Figure 2, the user is stepping through the addMethod to add the value 11. Figure 1 shows the UML class diagram with the TreeExample program which creates a LinkedBinarySearchTree instance called lbst, then proceeds to add various integer values to the tree. The following example illustrates an animated view for a linked tree structure. Initial classroom use has demonstrated the object viewers potential as an aid to student learning, while future research will explore their utility through controlled experiments. Multiple synchronized visualizations of an object, including complex data structures, are immediately available to users from the jGRASP debugger window or object workbench. Dean Hendrix Computer Science and Software Engineering Auburn University, AL 36849 ABSTRACT The jGRASP IDE provides new object viewers that automatically generate dynamic, state-based visualizations of objects and primitive variables in Java.
