The blackacteristics of an item of a consort atomic number 18 in like manner known as features, as well as are exposit by fields in Java. A field in a coterie definition is a variable that can store a lever which represents a specific property. The behaviors of an item of a track are also called operations, as well as are described utilize methods in Java. Fields as well as methods in a class definition are conjointly called members. For example we are thinking about a class CharStack to array the different ideas of object-oriented programming. // Source Filename: CharStack.java earth class CharStack { // Class name // Class Declarations: // (1) Fields: hidden char[] stackArray; // The array implementing the stack. offstage int topOfStack; // The top of the stack.

// (2) Constructor: common CharStack(int n) { stackArray = new char[n]; topOfStack = -1; } // (3) Methods: public malarkey push(char element) { stackArray[++topOfStack] = element; } public char pop() { return stackArray[topOfStack--]; } ! public char peek() { return stackArray[topOfStack]; } public boolean isEmpty() { return topOfStack < 0; } public boolean isFull() { return topOfStack == stackArray.length - 1; } } A class meter reading includes a group of member declarations. In the case of the class CharStack, it has two fields: ?stackArray, that is an array to hold the elements of the stack (in this instance characters) ?topOfStack, that denotes the top...If you want to get a full essay, order it on our website: OrderCustomPaper.com
