With this code, I'm still getting an error: Exception in thread "main" java.lang.NullPointerException. First, we used for loop to iterate each element. But we can take array input by using the method of the Scanner class. Creating an Array of Objects. There are three ways to create an array of objects in Java, 1) The Array of objects created with values. It tells the java compiler that system input will be provided. 2) The Array of objects creation without explicit values or with default values. Scanner split the input into token using delimiter pattern. Array in Java This textbook is designed for use in a two-course introduction to computer science. We know that an array is declared as follows. We use the Class_Name followed by a square bracket [] then object reference name to create an Array of Objects. How to Sort an ArrayList of Objects by Property in Java? JAVA ARRAY OF OBJECT, as defined by its name, stores an array of objects. The specified child already has a parent.
