Generics was added in Java 5 to providecompile-time type checkingand removing risk ofClassCastExceptionthat was common while working with collection classes. The whole collection framework was re-written to use generics for type-safety. Let’s see how generics help us using collection classes safel...
}while(x < 0); The code has some similarities with thewhileloop from the previous section. First, there is the assignment of the variablex, which is again3. On line 2, the loop starts with the keyworddoand the opening bracket{for the code block. On line 3, the value ofxis printed...
