    what is the error in this program

    class p3
    {
    public static void main(int age)
    {
    if(age>=18)
    {
    system.out.println(“eligible for election”);
    }
    else
    {
    system.out.println(“not eligible for election”);
    }
    }

    • 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!!

    • 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.

    This page is awesome For beginners…it is very helpful…give me example programs which will be useful for real time projects

  6. 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?

  7. 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:

  8. 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.

  9. 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

  11. Muqtasid khan says

    Write a program to accept the length of and breath of a rectangle using scanner class and display its area and perimeter

  12. anisha garg says

    can you please write a code on below question of complex number ??

    Print the sum, difference and product of two complex numbers by creating a class named ‘Complex’ with separate methods for each operation whose real and imaginary parts are entered by user.

  13. gausmohammad says

    please add more programs like matrix all operation and no. of time vowels occurrence in a string

  16. GESII LEIBOR says

  17. Siva kumar Nebarti says

    Hi where can i get real time example programs such as
    1 find out the no of persons in a room
    2 Find the electricity bill for one month

  18. Sachintha says

    I am new to java and I hope this beginnersbook.com would be very helpful to me. I am gonna start learning Java. Thank you very much.

    Program for password it must contain one upper case and lower case and number and size of password 8-15

    • 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
