All of these collections had no common interface. Need for a Separate Collection Framework in Javaīefore the Collection Framework(or before JDK 1.2) was introduced, the standard methods for grouping Java objects (or collections) were Arrays or Vectors, or Hashtables. However, an optimal object-oriented design always includes a framework with a collection of classes such that all the classes perform the same kind of task. In order to implement a new feature or a class, there is no need to define a framework. Collection framework implements various interfaces, Collection interface and Map interface () are the mainly used interfaces of Java Collection. ISRO CS Syllabus for Scientist/Engineer ExamĪ framework is a set of classes and interfaces which provide a ready-made architecture.Platform-neutral: Java code is independent of any particular hardware or software. It takes three operands: a condition to be evaluated, a value to be returned if the condition is true. Ternary Operator (Conditional Operator): The Ternary Operator, also known as the Conditional Operator, is a shorthand way of writing an if-else statement in some programming languages. Open Source: Readily available for development. Here are some common shorthand techniques with examples: 1.
