So an array of integers with size 3 and initial values are also initialized. The next method is int intArr4[] = IntStream.range(0, 10).toArray();. In this way, we are using Java 8 and its functionalities to create and initialize an array of the desired type. The prototype of the...
Syntax: <refVariable>=new <datatype>[size]; Example: After declaration, arr1=new int[3]; This can store three elements in the arr1 address.arr2=new float[5]; As the size is five, so it can store five elements.Length variable can be used with array reference variables to return the...
