package system does not exist

Very simple error ‘package system does not exist’- most probably you have used ‘err’ or ‘in’ or ‘out’ field of the ‘System’ class of ‘java.lang’ package but you have given small s instead of capital S in the class name System.

See the below code:

public class PackageSystemDoesNotExistError
{
public static void main(String args[])
{
system.out.println("package system does not exist error"); // here s is small
}
}

But in the following code:

public class PackageSystemDoesNotExistErrorSolved
{
public static void main(String args[])
{
System.out.println("package system does not exist error solved");//S is capital
}
}

Though System is not a package, as you have written system.out.println – three parts here (system, out and println) a package like statement, Java compiler considers it as package but as this package doesn’t exist, the error message is shown.

So the solution is just change the small s of system to capital S.
