7. Scrapbook

Since we are dealing with building blocks for the next few tutorials, it is not important to write entire applications with the class and main. This is done with a Java Scrapbook.

---

To create a Scrapbook, create a new project, which will contain the Scrapbooks, or just use the last used project. We have to use File New and Other.

---

Next, we have to double click Java so it will show more options under that folder.

---

In the Java Run/Debug subfolder, select Scrapbook Page. In the next, we set the name, such as ex7.

---

A simple java program is written. Next all text is selected, and the Execute the Selected Text toolbar is clicked. This toolbar should be near the top-right portion of screen.

// ex7.jpage
int a = 1;
int b = 3;
System.out.println("Sum = " + (a+b));
System.out.println("Difference = " + (a-b));
