Consider a situation, when we have two persons with the same name, Piyush, in the same class. Whenever we need to differentiate them definitely we would have to use some additional information along with their name, like either the area, if they live in a different area or their mother’s or father’s name, etc.The same situation can arise in your C++ applications. For example, you might be writing some code that has a function called xyz() and there is another library available which is also having same function xyz(). Now the compiler has no way of knowing which version of ... Read More

Yes. The only condition is to have one public class in separate java file.
There is no global variables support in Java. Static variables can be used as an alternate solution for global variables.
Yes, from Java 8 onwards, java.util.concurrent.atomic package contains classes which support atomic operations on single variables preventing race conditions or do not face synchronization issues. All classes in the atomic package have get/set methods. Each set method has a happens-before relationship with any subsequent get() method call on the same variable. import java.util.concurrent.atomic.AtomicInteger; class AtomicCounter { private AtomicInteger counter = new AtomicInteger(0); public void increment() { counter.incrementAndGet(); } public void decrement() { counter.decrementAndGet(); } public int value() { return counter.get(); } }
Yes, a java program is first compiled into bytecode which JRE can understand. ByteCode is then interpreted by the JVM making it as interpreted language.
Narrowing refers to passing a higher size data type like int to a lower size data type like short. It may lead to data loss. Casting is required for narrowing conversion. Following program output will be 44. public class MyFirstJavaProgram { public static void main(String []args) { int a = 300; byte b = (byte)a; // narrowing System.out.println(b); } }
