Autoboxing
Up through version 4 of Java, an assignment like
Integer b;
b= 25;
int i;
i= b;
were illegal, because the types of the variable and expression did not match —one is an int and the other i

Precedences of operators
You know that multiplication * takes precedence over addition +, e.g. the expression 5 + 4 * 3 is evaluated as if it were parenthesized like this: 5 + (4 * 3). Mathematics has
Eclipse Tutorial
We show you how to install and use the IDE (Integrated Development Environment) Eclipse. Installation Process Before you install Eclipse (now version 3.2.2), make sure that you have
Function calls
You have seen function calls since high school, like sqrt(25) abs(-7) cos(0) min(5, 7) / square root of 25. Its value is 5.0. / absolute value of -7. Its value is 7. / cosine of angle 0
/* An instance is a point (x, y) in the plane */ public class Point { /* The x and y coordinates of a point */ private double x; private double y; /* Constructor: a point (b, c) */ public Point(double
Return Statements
Execution of a return statement terminates execution of the method body and, hence, of the method call. The return statement in the body of a function differs from the return stateme
Method Headers
We summarize method headers, define the signature of a method, and discuss its use. This material is covered in more detail in the course text, Gries/Gries. A method declaration consist
Declaring local variables where they belong, logically speaking
We discuss the placement of local variable declarations. Generally, the declarations should go where they belong, logically speaking, an
Local variables
A local variable is a variable that is declared within a method body. The program you see has two different
local variables, both named temp.
The syntax of a local variable declaration
Specifications of methods
You know what the first function mini does, because its specification, in the comment preceding it,
tells you. You don’t need the function body —which we show you now.
