Java Programming 

This section is design for object oriented programming  language and most powerful language of (OOPS) which is called  JAVA programming for beginner. In this section you can learn how to start coding in Java programming. You can learn  how to create various types of Function in Java programming  Link:  http://sujitvital89.blogspot.com/p/blog-page_18.html. And you can also create programming for string  in Java Link: https://sujitvital89.blogspot.in/p/blog-page_20.html .
1)   Write a Hello word Program in Java?

Import java.io*;
Class Hello
{
Public static void main (String args[])
{
System.out.println(“Hello My First  Java programming”);
}
}
Java programming used few common words meaning
Used Word in Java
Meaning of Word and use’s
Import
Used for import of file
Java
Programming Name
Io
In and out data in Java
Class
Object
Hello
Name
Public
Accessible any ware 
Static
Keyword
Void
Keyword , Not Return Value
String
Used for text  pass the string value like: Hello My First  Java programming
Main
Object , Program starting to execution 
Args[]
Pass argument in java
System.out.println
Print output in given block
through io exception
Any exception showing


Output = Hello My First Java programming

2) Write a program in adding two words in Java?


Import Java .io.*;
Class addword
{
Public static void main(String args[]) throws IOException
{
InputStreamReader in =new InputStreamReader (System.in);
Int a,b,c;
System.out.println(“Enter the First Value:”);
a=Integer.ParseInt(br.readLine();
System.out.printLn(“Enter the Second Value:”);
b=Integer.ParseInt(br.readLine();
c=a+b;
System.out.println(“Sum of Total=”+c);
}
}

Input

Enter the First Value : 10
Enter the Second Value:20
Sum of Total= 30

     3)     Write a program and calculate area in Java?

import java.io.*;
class area;
{
public static void main (String args[]) throws IOE xception
{
InputStreamReader in=new InputStreamReader(System.in);
BufferedReader br=new BufferedReader(in);
Int l,b,m;
System.out.Println(“Enter The Length  of Area:”);
l=Integer.ParseInt(br.readLine());  // used for reading of line
System.out.Println(“Enter The Breath  of Area:”);
b=Integer.ParseInt(br.readLine());
m=l*b;
System.out.Println(“Area=”+m);
}
}

Input
Output
Enter The Length  of Area: 20
Enter The Breath  of Area:20
Area= 400

 4) Write a program of Circle in Java?

import java.io.*;
Class circle
{
Public static void main(String args[]) throws IOException
{
InputStreamReader in=new InputStreamReader(System.in)
BufferedReader br=new BufferedReader(in);
Int a,o;
System.out.println(“Enter the Area:”);
a=Integer.ParseInt(br.readLine());
o=a*2;
System.out.println(“Total Area=”+o);
}
}

Input
Output
Enter the Area: 20
Total Area= 40
    
      5)   Write a program to find out total and average marks of student who has appearing in examination.

import java.io.*;
Class student
{
Public static void main (String args[])throws IOException
{
inputStreamReader in=new InputStreamReader(System.in)
int m,n,o,p,q,r,s; // Local Variable
System.out.println(“Enter The Marks of Math:”);
m=Integer.Parse.Int(br.readLine());
System.out.println(“Enter The Marks of English:”);
n=Integer.Parse.Int(br.readLine());
System.out.println(“Enter The Marks of Science:”);
o=Integer.Parse.Int(br.readLine());
System.out.println(“Enter The Marks of S.Science:”);
p=Integer.Parse.Int(br.readLine());
q=m+n+o+p;
system.out.println(“Total Marks of Student=”+q);
r=q/4;
System.out.println(Average Marks of Student=”+r);
}
}

Input
Output
Enter The Marks of Math: 70
Enter The Marks of English:60
Enter The Marks of Science:80
Enter The Marks of S. Science:90
Total Marks of Student= 300
Average Marks of Student= 75

     6) Write a program if a person goes to bank for withdrawn certain amount of money. If the bank given change in ` 2000 Note and  Rs 100  find out how many  Rs 2000 note and  how many Rs100  note the person received.

import java.io.*;
Class BankMoney
{
Public static void main(String arge[])throws IOException
{
BufferedReader br=new BufferedReader(System.in);
Int a,b,c,d,e;
System.out.Println(“Enter The Amount:”);
a=Integer.Parse.Int(br.readLine());
b=a/2000;
c=a%2000;
d=a/100;
e=a%100;
System.out.Println(“Number of 2000 `=+b);
System.out.Println(“Number of 100 `=+d);
}
}

Input
Output
Enter The Amount: 2500
Number of 2000 Rs = 1
Number of 100 Rs = 5

7)   Write a program to generate natural number in Java?

import.java.io.*;
class number
{
Public static void main (String args[])throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
Int m;
For(m=1; m=<11;m++)
{
System.out.println(“m+”,”);
}
}

Output: 1,2,3,4,5,6,7,8,9,10.

Looping in Java

     8)Write a program in Java and generate odd number between 50 to 100.

import.java.io.*;
Class natural
{
Public static void main (String args[])throws IOException
{
BufferedReader br=new BufferedReader(new ImputStreamReader(System.in));
Int n;
for(n=49;n<=51*2;n++)
if(n%2!=0)
{
System.out.println(n+””);
}
}
} 

 9) Write a program to generate even number between 200 to 80.

import java.io.*;
class evennum
{
Public static void main(String args[])throws IOException
{
BufferedReader br=new BufferedReader(new ImputStreamReader(System.in));
Int m;
for(m=80;m<=101*2;m++) // if number is not divided by 2 it means it’s even number.
if(m%2==0)
{
System.out.println(m+””);
}
}
}

  10) Write a program to generate natural number Up to n?

import java.io.*;
class nnumber
{
Public static void main(String args[])throws IOException
{
BufferedReader br=new BufferedReader(new ImputStreamReader(System.in));
Int p,q; //p is looping variable and q for sorting data.
for(q=1;q<=p;q++)
{
System.out.println(q);
}
}

}

 11) Write a program to generate natural numbers between given range?

import java.io.*;
class rangenum
{
Public static void main(String args[])throws IOException
{
BufferedReader br=new BufferedReader(new ImputStreamReader(System.in));
Int a,b,c;
System.print.out.ln(“Enter The First Number of Range:”);
a=integer.parse.Int(br.readLine());
System.print.out.ln(“Enter The Second Number of Range:”);
b=integer.parse.Int(br.readLine());
for (c=a; c<=b; c++ )
{
System.out.println(c);
}
}
}


Input
Output
Enter The First Number of Range: 1
Enter The Second Number of Range:4
1,2,3,4

12) Write a program to print your name 4 times?

import java.io.*;
class rangenum
{
Public static void main(String args[])throws IOException
{
BufferedReader br=new BufferedReader(new ImputStreamReader(System.in));
Int x ;
for (x=1;x<=5;x++ )
{
System.out.println(x+”Kumar”);
}
}
}

Output: Kumar, Kumar, Kumar, Kumar, Kumar
