Creating Object

Assume I have 2 classes one(Cse412lab2) contains the main method and the other (StackOfmethod) contains different other methods

Creating object of StackOfmethod class

StackOfmethod ob1=new StackOfmethod();

Overloading Methods

public void method(){
System.out.println("Nothing to print");
}

public void method(String name){
System.out.println("Hello " +name);

}

Constructor

public StackOfmethod(String name, String Age){
System.out.println("Hello "+name);
System.out.println("Your Age " + Age );

}

*** class name StackOfmethod

Access private variable

private int x=10;
private int y=15;
public void accessPrivateVariable(){
int res=0;

res =x+y;
System.out.println(res);
}

** variable out side any method are called instance variable

First run Host.java
then run Guest.java

Java Database Connection

Please find the following link of netbeans project for java database connection

Please note that u have to create a database first using xampp with the name "cse412lab"
Then import the cse412lab.sql (available in the rar file) file while you are inside the database "cse412lab"

Now if you run the program using netbeans your program is likely to run without any error.

Program

import java.lang.Math;
class b4
{
   public static void main (String[] args) {
       double a=56.34;
       double y=Math.sin(a);
       System.out.printf("The sin value of %f is %f",a,y);
}
}
Output
The sin value of 56.340000 is -0.207157

Program

class it{
   public static void main (String[] args) {
       int i,j;
for(i=1;i<=5;i++)
{

for(j=1;j<=i;j++)

Fibonaci

class fibonaci{
public static void main (String[] args) {
int n,m=100,x,y;
n=0; x=1;
System.out.printf("%d\t",x);

while(x<=m)
{
y=n+x;
System.out.printf("% d\t",y);
n=x; x=y;
}
}
}
Output

       float C;
       System.out.println("Enter a number");
       F = input.nextInt();
       C=(F-32)/18;
       System.out.printf("Converted Celsius Heat is %.2f",C);
}
}

Output
Enter a number
420
Converted Celsius Heat is 21.56

Program

import java.lang.Math;
class b1
{
    public static void main (String[] args) {
        double a=56.34;
        double y=Math.sqrt(a);
        System.out.printf("The Square Root of %f is %f",a,y);
}
}
Output
