To understand a programming language you must practice the programs, this way you can learn the language faster. This page includes java programs on various java topics such as control statements, loops, classes & objects, functions, arrays etc. All the programs are tested and provided with the output. If you new to java and want to learn java before trying out these program, then read my Core Java Tutorials.

A function doesn’t contain a main method
pratham programmer says
your s should not be small in the statement “system. out. print…” . It should be capital S
Arpita Mandal says
Hey..there is a syntax error in your program!
The “s” of “system” must be in caps…that is,
It should be —
System.out.println(“eligible…”);
I hope it helps!!
Shravya says
} bracket error
Last } bracket are required
Shweta says
You can’t pass any argument in main method
Vamshi Krishna says
actually we can, they’re called as “command line arguments”
Ram panwar says
Yes we can pass argument in main function using command line argument..as a string
Deepak Kumar says
You can pass arguments in main method but only as String…..
priya says
public static void main(String []args) will come instead of public Static void main(int age)
Isuru Harischandra says
“int age” should be “String[] args” / “String args[]” / “String[] arg” / “String arg[]”
Mohit Tyagi says
Four mistakes:
1. main method should have String []args as arguments instead of age. Use public static void main(String args[])
2. age should be declared as a variable before using. Use int age=10;
3. System.out.println instead of system.out.println.
4.Closing bracket fro class p3 missing. Use } at last.
geojeet tom says
haven’t put the third closed curly brackets
sudhan says
Give System.out.print
And close curly braces at end
Bhanu pratap singh yadav says
main function arguments are (String[] args)

best java tutorial examples ever

This page is awesome For beginners…it is very helpful…give me example programs which will be useful for real time projects
Sheldon says
How can I take an array for example five separate words and place them on separate lines evenly using astericks to make up the number on both ends in relation to the number entered by the user? Is a program to do this possible?
Anil says
console application that receives any size of matrix and one parameter which is the Manhattan distance, this is K.
The result should be Yes/No. Yes if there are any two similar items (integers) in the matrix that are in a distance of K from each other or less.
Input: 1. Number of rows. 2. Matrix rows one line after the other in a new line between each matrix line. 3. K value. Output YES/NO Here is a sample for an input and output:
deepika says
can you kindly provide program for the following
java a program to create an array of 10 integers. Accept values from the user in that array. Input another number from the user and find out how many numbers are equal to the number passed, how many are greater and how many are less than the number passed.
Nikhil Satpute says
# Suppose 450 is 3 digit number ….So 3 is its digit length. In that way calculate 5 digit random number ….do not run by using range ….get random number using length itself

Anto says
What “System.out.println(“”)” means?
Please reply
Rakesh Gurung says
If we type
System.out.println(“This is java”);
This will display the output :This is java
where as if you are taking about just the statement
System.out.println(“”);
Then it will print the blank or space in console
