The difference between the GetMessage () and ToString () methods of E in Exception e:
Example code 1:
Public Classtestinfo {
Privatestatic String str =null;
publicstatic void Main (string[] args) {
System.out.println ("TestException");
try{
if (str.equals ("name")) {
System.out.println ("TestException");
}
}catch (Exception e) {
System.out.println (E.tostring ());
System.out.println (E.getmessage ());
}
}
}
Output Result:
; font-family: "microsoft=" "background-color:=" "/>Null
Example code 2:
public class TestInfo {
private static int m = 0;
public static Voidmain (string[] args) {
System.out.println ("TestException");
try {
m = 899/0;
} catch (Exception e) {
System.out.println (E.tostring ());
System.out.println (E.getmessage ());
}
}
}
Output Result:
Java.lang.ArithmeticException:/by Zero
/by Zero
Summary: As you can see, the information obtained by e.tostring () includes the exception type and the exception detail message, while E.getmessage () just gets the verbose message string for the exception.
