The first item in this MTA Introduction to Programming Using Java review is a quote bylined, “evaluate the following code segments at random and you will not find the answer.” If you want to evaluate the following code segment, you need to evaluate the following code:
The first problem is how should you complete the above code? There are many potential answers to that question. In this MTA Introduction to Programming Using Java review, one suggested answer is to “drop down on the drop-down menu and choose the appropriate code segment” and then to “fill in the blanks.” This suggested solution solves the problem of finding the right way to evaluate code. In the second part of the article, I will describe the appropriate code segment.
The second item in the MTA Introduction to Programming Using Java review, a quote bylines, says, “dropped-down arrows indicate an alternative answer option in the Netscape Netbeans dialog box.” The question in this dialog box is, “You dropped-down arrows indicate an alternative answer option in the Netscape Netbeans dialog box.” How should you complete the above code? In this Netscape Netbeans dialog box, you may see three check boxes: Pause, Stop, and Go. If you click on any one of the check boxes, the corresponding program is prompted to start or stop the application.
To complete the above example, you would move your cursor to the left-just-past-the-cancel button. Then, drop-down-arrows appear, indicating the current tab (if there are more than one) to be closed and the resulting code segment. You would then click “OK”. An appropriate Netscape Netbeans tutorial or package would provide additional details about using the hotspots. If there are no additional steps, this Netscape example should solve your problem about “how should you complete the code”.
In the previous example, you used a drop-down menu to select “Pradesh” in the output. To evaluate the answer based on this information, the “row number” is the column number for that state or country. The “rows” and “col” tags indicate the column and row labels, respectively. If your browser does not automatically replace the text label with a drop-down menu, you can use quotation marks, hyphens, or braces to mark the text. After selecting the appropriate option, you enter the selected text into the text box. The “rows” and “col” tags indicate the column and row names, respectively, of the data source.
The next example shows how to split a long code segment into two smaller ones. The first group of long lines will display the name of the subject in the first frame. The second group of short lines will display the name of the source file in the second frame. You may need to adjust the properties of the split windows in your Java program to display both source files at the same time. If you choose to create two separate windows by means of Java programming, then you must give one of the windows a longer duration than the other window.
To check your answers, click on the “Submit” button. A message containing the computed result will appear. Click on “recalculate” to compare the new result with the old one. If you find any incorrect answer, you may press “undo” to replace it with the correct answer. Each correct selection is worth one point. If there are more incorrect answers than correct selections, the difference in score is adjusted to allow for rounding.
