Java class problem

I'm trying to make a class that has a method to convert a celsius to two
values, approximate fahrenheit, and accurate fahrenheit. The method is below.
public static String celsFahr()
// This method will print "Close enough"
// If the values of approximate fahrenheit
// are within two degrees of each other and
// it will print "Will not do" if those two
// values are not within
// two degrees of each other
{
appFahr = cels * 2 + 32;
// Formula to convert
// celsius to approximate fahrenheit
fahr = (9 / 5) * cels + 32;
// Formula to convert celsius to accurate fahrenheit
lessFahr = fahr - 3;
greatFahr = fahr + 3;
if ((appFahr <= fahr) && (appFahr > lessFahr) || (appFahr >= fahr) && (appFahr
< greatFahr))
{
return System.out.println("Close enough");
}
else
{
return System.out.println("Will not do");
}
} // End of method
When I try to compile the .java file, I get the following error.
FahrClss.java:90: incompatible types
found : void
required: java.lang.String
return System.out.println("Close enough");
^
FahrClss.java:94: incompatible types
found : void
required: java.lang.String
return System.out.println("Will not do");

I tried importing java.lang.String at the top of my class.
import java.lang.String;
Unfortunately, that did not work. What am I doing wrong. My entire class is
below.
public class FahrClss
{
static int cels; // Stores the value for celsius
static int appFahr; // Stores the value
// of approximate fahrenheit
static int fahr; // Stores the value of
// exact fahrenheit
static int lessFahr; // Stores the value of
// fahr - 3
static int greatFahr; // Stores the value of
// fahr + 3
public FahrClss(int newCels)
// Start of parameterized constructor
{
cels = newCels; // Stores the value passed
// from newCels
}
public FahrClss()
// Start of default constructor
{
cels = 0; // object gets set to 0
}
public static int getCels()
// Start of observer method
{
return cels; // Returns the value of
// cels to driver class
}
public static int getAppFahr()
// Start of observer method
{
return cels * 2 + 32; // Returns the value of
// approximate fahrenheit to driver class
}
public static int getFahr()
// Start of observer method
{
return (9 / 5) * cels + 32; // Returns the value of
// fahrenheit to driver class
}
public static String celsFahr()
// This method will print "Close enough"
// If the values of approximate fahrenheit
// are within two degrees of each other and
// it will print "Will not do" if those two
// values are not within
// two degrees of each other
{
appFahr = cels * 2 + 32;
// Formula to convert
// celsius to approximate fahrenheit
fahr = (9 / 5) * cels + 32;
// Formula to convert celsius to accurate fahrenheit
lessFahr = fahr - 3;
greatFahr = fahr + 3;
if ((appFahr <= fahr) && (appFahr > lessFahr) || (appFahr >= fahr) && (appFahr
< greatFahr))
{
return System.out.println("Close enough");
}
else
{
return System.out.println("Will not do");
}
} // End of method
} // End of class
