The document discusses a trainee's progress in typing speed and jobs applied over 3 weeks, achieving targets of 21, 23, and 27 words per minute and applying to 3 companies while waiting to hear back on 2 applications. It also provides an overview of method overloading and constructor overloading in Java with examples.

6. What is Method
• A Java method is a collection of statements that are grouped
together to perform an operation
• A class can contain any number of methods.
• Methods can be with parameter and without parameter.
• The parameter in a method are called type signature.

7. Method Overloading
• Two or more methods within the same class that share the same
name, but with different parameter declarations (type signatures).
• The process is referred to as method overloading.
• Overloading methods demonstrate the concept of polymorphism.
• Overloaded methods may have different return types.
• When java encounters a call to an overloaded method, it simply executes the
version of the method whose parameters match the arguments used in the
call.

8. Example
•
{
public class example_1
void square(int p1, int p2)
int n1;
int n2;
example_1()
{
n1 = 10;
n2 = 20;
}
void square()
{
System.out.println("The Square is " + n1 * n2);
}
void square(int p1)
{
n1 = p1;
System.out.println("The Square is " + n1 *
n2);
}
{
n1 = p1;
n2 = p2;
System.out.println("The Square is " +
n1 * n2);
}
public static void main(String args[])
{
example_1 obj1 = new example_1();
obj1.square();
obj1.square(4);
obj1.square(7,8);
}
}

9. Constructor
•
•
•
•
Special type of method
A constructor initialize an object immediately upon creation
Name of constructor must be same as name of Class
Once defined, the constructor is automatically called immediately after
the object is created before the new operator compleates
• They do not specify any return type not even void

10. Constructor Overloading
• Constructors are methods that can be overloaded, just like any
other method in a class.
• Constructors having the same name with different parameter
list is called constructor overloading.

11. class Point
{
int x;
int y;
Point(int a, int b)
{
x = a;
y = b;
}}
class Circle
{
int originX;
int originY;
int radius;
Circle()
{
originX = 5;
originY = 5;
radius = 3;
}
Circle(int x1, int y1, int r)
{
originX = x1;
originY = y1;
radius = r;
}
Example
Circle(Point p, int r)
{
originX = p.x;
originY = p.y;
radius = r;
}
void display()
{
System.out.println("--Center at " + originX
+ " and " + originY);
System.out.println("Radius = " + radius);
}
public static void main(String args[])
{
Circle c1 = new Circle();
Circle c2 = new Circle(10,20,5);
Circle c3 = new Circle(new Point(15,25),10);
c1.display();
c2.display();
c3.display();
}}
