// Also shows String concatenation, the length() method of the String class,
// and escape sequences \n (newline) and \" (double quote)

/* Program output:

Printing the rectangle
java.awt.Rectangle[x=5,y=10,width=20,height=30]

The string s1, "Printing the rectangle" has 22 characters.

Printing the rectangle (after moving it)
java.awt.Rectangle[x=20,y=35,width=20,height=30]

The string s1, "Printing the rectangle (after moving it)" has 40 characters.
