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 lower case "s" instead of upper case "S" in the class name System. Remember Java is case sensitive.
See the below code:
system.out.println("package system does not exist error"); // here s is in lower case
But in the following code:
System.out.println("package system does not exist error solved");//S is in upper case
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 lower case "s" of system to upper case "S".
