What is the error in the following program written in Java?

public class Testing$\{$

public static void main$($String$[]$ args$)\{$

int x $=7$;

double y $=13\mathrm{.}0$;

System.out.println$($x $<4$ && x $>5)$;

System.out.println$(13<=$ y $<=16)$;

$\}$

$\}$

Cannot chain Boolean comparators together

Cannot compare double y to integer values $13$ and $15$

The value x cannot be less than $4$ and greater than $5$

Double y must be declared using $15\mathrm{.}0$f
