This is one of the suggested ways of implementing a generic collection inEffective Java; Item 26. No type errors, no need to cast the array repeatedly.Howeverthis triggers a warning because it is potentially dangerous, and should be used with caution. As detailed in the comments, thisObject[...

You can do it easily by using StringTokenizer class defined in java.util package. voidmain(){inti=0;intn[]=newint[2];//for integer array of numbersString st="[1,2]"; StringTokenizer stk=newStringTokenizer(st,"[,]");//"[,]" is the delimeterString s[]=newString[2];//for Stri...
Note:WhengetArrayis used to materialize a base type that maps to a primitive data type, then it is implementation-defined whether the array returned is an array of that primitive data type or an array ofObject. Returns: an array in the Java programming language that contains the ordered elem...
In object-oriented computer programming, a null object is an object with no referenced value or with defined neutral ("null") behavior. The null object design pattern describes the uses of such objects and their behavior (or lack thereof). ...
Using Comparable to Sort Array of Objects in Java A Comparable interface in Java is used to order user-defined objects. Here, the Student class implements Comparable so that we can use Arrays.sort() to sort an array of Student class objects. The Student class has three member variables name...
address of the first element. Here, we must notice that we need to pass only the name of the array in the function which is intended to accept an array. The array defined as the formal parameter will automatically refer to the array specified by the array name defined as an actual ...

Array Algorithms are defined as functional algorithms where each step of the algorithm results in a function being applied to an array, producing an array result. Array algorithms are compared with non-array algorithms. A brief rationale for teaching array algorithms is given together with an exampl...
