Modifier and Type | Field and Description |
---|---|
static Level |
ALL
OFF is a special level that can be used to turn off logging.
|
static Level |
CONFIG
CONFIG is a message level for static configuration messages.
|
static Level |
FINE
FINE is a message level providing tracing information.
|
static Level |
FINER
FINER indicates a fairly detailed tracing message.
|
static Level |
FINEST
FINEST indicates a highly detailed tracing message.
|
static Level |
INFO
INFO is a message level for informational messages.
|
static Level |
OFF
ALL indicates that all messages should be logged.
|
static Level |
SEVERE
SEVERE is a message level indicating a serious failure.
|
static Level |
WARNING
WARNING is a message level indicating a potential problem.

Level(java.lang.String name,
int value)
Creates a named Level with the given integer value.

.public static final Level SEVERE
In general SEVERE messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to system administrators. This level is initialized to .
public static final Level WARNING
In general WARNING messages should describe events that will be of interest to end users or system managers, or which indicate potential problems. This level is initialized to .
public static final Level INFO
Typically INFO messages will be written to the console or its equivalent. So the INFO level should only be used for reasonably significant messages that will make sense to end users and system admins. This level is initialized to .
public static final Level CONFIG
CONFIG messages are intended to provide a variety of static configuration information, to assist in debugging problems that may be associated with particular configurations. For example, CONFIG message might include the CPU type, the graphics depth, the GUI look-and-feel, etc. This level is initialized to .
public static final Level FINE
All of FINE, FINER, and FINEST are intended for relatively detailed tracing. The exact meaning of the three levels will vary between subsystems, but in general, FINEST should be used for the most voluminous detailed output, FINER for somewhat less detailed output, and FINE for the lowest volume (and most important) messages.
In general the FINE level should be used for information that will be broadly interesting to developers who do not have a specialized interest in the specific subsystem.
FINE messages might include things like minor (recoverable) failures. Issues indicating potential performance problems are also worth logging as FINE. This level is initialized to .
