Then we return the array using return array1. In the main() method, we call method1() and convert it to a String using Arrays.toString() and we can see the array of all the values in the output. import java.util
In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Jav...
Method 2: Return a String in Java Using return Statement Another way to return a string is by using a “return” statement at the end of the method. When a programmer writes a program, the compiler examines the return type. If the return type is set as “String”, then the added str...

A Cryptographic Service Provider (provider) refers to a package (or a set of packages) that supply a concrete implementation of a subset of the cryptography aspects of the JDK Security API. The java.security.Provider class encapsulates the notion of a security provider in the Java platform. It...
This document describes what you need to do in order to integrate your provider into Java SE so that algorithms and other services can be found when Java Security API clients request them.
This tutorial demonstrates how to solve the attempt to invoke a virtual method on a null object reference error in Java.
