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”);
>
>

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!!

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.

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:
