Question

java prog

The following statements are either True or false | An instance variable or method belongs to an instance of a class. Its use is associated with individual instances. A variable defined inside a method is referred to as a local variable. Exception handling separates error-handling code from normal programming tasks, thus making programs easier to read and to modify. When an exception occurs in a method, the method does not exit immediately if it does not catch the exception. A static method is a method that cannot be invoked without using instances.

Answer 1

1) An instance variable or method belongs to an instance of a class. Its use is associated with individual instances. This statement is true.

public class Employee {

// this an instance variable
public String Employee_name;
}

2) A variable defined inside a method is referred to as a local variable. This statement is true.

public void Age()
{
// local variable age
int age = 20;
System.out.println("Value of age is : " + age);
}

3) Exception handling separates error-handling code from normal programming tasks, thus making programs easier to read and to modify. This statement is true. In Java we use try and catch statements to handle the exception. Catch block is used to handle the exception by declaring the type of exception ( for example : IOException, ArithmeticException ) within the parameter.

4) When an exception occurs in a method, the method does not exit immediately if it does not catch the exception. This statement is false . Exception handling provides a technique for detecting failure and controlling the program's response to it. Catch statement is used to define a block of code to be executed, if an error occurs.

5) A static method is a method that cannot be invoked without using instances. This statement is false. Static method in can be called without creating an object of class.
