Sample text

We now show how to solve the same problem in a slightly different way by using a class. We can think of each word in the passage as an object with two attributes—the letters in the word and the number of times it appears. ” class WordInfo { String word; int freq = 0; WordInfo(String w, int f) { word = w; freq = f; } void incrFreq() { freq++; } } //end class WordInfo The class has two fields: word and freq. It has a constructor to initialize a WordInfo object to a given word and frequency. It also has a method to add 1 to the frequency of a word.

We can use b or c to access Ball Joint data. If we have the address of an object, we have all the information we need to manipulate the object. 95); Assume these statements create the situation shown in Figure 2-7. 95 3472 5768 a b Figure 2-7. After creation of two Part objects Suppose we execute this statement: a = b; The situation changes to that shown in Figure 2-8. 95 5768 5768 a b Figure 2-8. After assigning b to a Both a and b now have the same value, 5768. They both point to the Ball Joint object.

Within a program, each attribute is represented by an appropriate variable; for instance, a String variable can represent name, an int variable can represent age, a char variable can represent gender, a double variable can represent height, and so on. We normally use the term field names (or, simply, fields) to refer to these variables. Thus, the state of an object is defined by the values in its fields. In addition, we will need methods to set and/or change the values of the fields as well as to retrieve their values.
