Java Programming

Void methods must have at least one parameter.

An identifier can be declared anywhere including within a class, and outside of every method definition (and every block).

Just like the nesting of loops, Java allows the nesting of methods.

In order to use the method isUpperCase of the class Character, the package java.lang must be explicitly imported.

A local identifier is an identifier that is declared within a method or block and that is visible only within that method or block.

Void methods use the return statement to return the value 0.

The class Math is contained in the package java.math.

If a formal parameter is a variable of a primitive data type, then after copying the value of the actual parameter, there is no connection between the formal and actual parameter.

When a program executes, the first statement to execute is always the first statement in the main method.

Suppose that the following statement is included in a program. import static java.lang.Math.*; After this statement, a static method of the class Math can be called using just the method name.

You can use the class String to pass strings as parameters to a method and change the actual parameter.

Methods are also called modules.

An actual parameter is a variable or expression listed in a method call.

Strings assigned to StringBuffer variables can be altered.

Reference variables as parameters allow you to return more than one value from a method.

The return statement must be the last line of the method.

The word static is a return type in Java.

To use a predefined method, you must know the code in the body of the method.

In Java, return is a reserved word.

Actual and formal parameters have a one-to-one correspondence.
