Answer:
The answer to this question is given below in the explanation section.
Explanation:
When you will run the given code of java in this question. You will get an error and nothing will get printed in the response of the result. Because, in Java, you can't add the two array objects. The reason behind it, java does not support operator overloading. You cannot use the plus operator to add two arrays in Java
. It will give you the compile-time error.
There is a method to add two arrays in the Java program is to iterate over them and add individual elements and store them into a new array. This also becomes complex, if you having arrays of different sizes. To go through this method, you have to build a method that will through an illegal exception in case of a mismatch in the sizes of the arrays.
As in the given code, when you execute the first print statement:
System.out.println(num1.get(0)+1);
It will produce error because first type is object and second is int. So, you cannot add object and int value.
When you will execute the given second print statement:
System.out.println(num1.get(1)+ num2.get(0));
it will also produce error, because you cannot add object in Java using + binary operator because in this statement first and second type are both objects.
Answer:
Following are the code to this question:
Counter T = new Counter(1, 100); //creating Counter class object and call its parameterized constructor
Thread T1 = new Thread(new Runnable() //creating Thread object T1.
{
public void run() //define run method
{
T.countRange(); //call countRange method
}
});
Thread T2 = new Thread(new Runnable() //creating another object "T2" of Thread.
{
public void run() //define run method
{
T.countRange(); //call countRange method
}
});
T1.start(); //start Thread T1
T2.start(); //start Thread T2
Explanation:
Description of the above code as follows:
- In the given code, inside the main method the Counter class object "T" is created, that calls its parameterized constructor, which accepts two integer value that is "1 and 100".
- In the next step, thread class object T1 and T2, is created, which uses run method, in which it called the countRange method inside the method a for loop is declared that prints value between parameter value.
- In the last step, the start method is called, which uses the run method to call countRange method.
