  Introduction:
  
  Loops are constructs that control repeated executions of a block of statements. The concept of looping is fundamental to programming. Java provides three types of loop statements: while loops, do-while loops, and for loops. In this chapter students will learned how to use these types of loops. At the end of the chapter student will learn how to use the control an break controls with loops. Many related programming problems will be discussed through the chapter.

Section 5
- Chapter Five:
  
  Introduction:
  
  A method is a collection of statements grouped together to perform an operation. In earlier chapters students have used predefined methods such as System.out.println, JOption-Pane.showMessageDialog, Integer.parseInt, Math.pow, and Math.random. These methods are defined in the Java library. In this chapter, students will learn how to define their own methods and apply method abstraction to solve complex problems. Many related programming problems will be discussed through the chapter.

  After completing this chapter the student should be able:
  
  To define methods.

  overloading.

Section 6
- Chapter Six:
  
  Introduction:
  
  An array is used to store a collection of data. It is used to define a collection of variables of the same type. Instead of declaring individual variables, such as number0, number1, and number99, the student can declare one array variable such as
  numbers and use numbers[0], numbers[1], and numbers[99] to represent individual
  variables. This chapter introduces single-dimensional arrays and show how to declare array variables, create arrays, and process arrays using indexed variables. Many related programming problems will be discussed through the chapter.
  
  Objectives:
  
  After completing this chapter the student should be able:
  
  To describe why arrays are necessary in programming.
  
  To declare array reference variables and create arrays.
  
  To initialize the values in an array.
  
  To access array elements using indexed variables.
  
  To program common array operations (displaying arrays,
  summing all elements, finding min and max elements.
  
  To simplify programming using the for-each loops.
  
  To copy contents from one array to another.
  
  To develop and invoke methods with array arguments and return
  value.
  
  To define a method with variable-length argument list.
  
  To search elements using the linear or binary search algorithm.
  
  To sort an array using the selection sort.
