To call one constructor from another in Java, you can use the this keyword. Here is an example: public class MyClass { private int x; private int y; public MyClass() { // Default constructor this(0, 0); } public MyClass(int x, int y) { // Constructor with arguments this.x =...
1. The SampleClass has a private constructor, which means it cannot be instantiated directly. 2. To work around this, Java Reflection is used to access the private constructor and make it accessible. 3. Once accessible, the constructor is invoked with “Mocked Value”, creating an instance of...
In Java, a thread is a lightweight sub-process allowing concurrent execution of two or more program parts. Each thread has its call stack but shares the same memory space as the other threads in the process. This enables threads to efficiently share data and resources without the need for...
