You will see an output of the entered name/word above the input box and then you will see the normal input box again just like before. In this topic, we are going to learn how to write a program to print Pascal triangle patterns using numbers using user input in the Java programming language. call_user_method_array(method, obj, params) Parameters. array_column () Returns the values from a single column in the input array. arrayName: is an identifier.
