java - Handle all exceptions -

i used logback logging java application. how can handle exceptions in app logback

my test config

    <appender name="exceptions" class="ch.qos.logback.core.fileappender">         <filter class="ch.qos.logback.core.filter.evaluatorfilter">             <evaluator>                 <expression>java.lang.exception.class.isinstance(throwable)</expression>             </evaluator>             <onmatch>accept</onmatch>         </filter>         <file>exceptions.log</file>         <append>true</append>         <encoder>             <pattern>%d{hh:mm:ss.sss} %-5level %logger{36} - %msg%n</pattern>             <immediateflush>false</immediateflush>         </encoder>     </appender> 

assuming mean catching exceptions, not caught: can define uncaught exceptions handler in code, possible:

private static void setdefaultuncaughtexceptionhandler() {     try {         thread.setdefaultuncaughtexceptionhandler(new thread.uncaughtexceptionhandler() {             @override             public void uncaughtexception(thread t, throwable e) {                 logger.error("uncaught exception detected in thread " + t, e);             }         });     } catch (securityexception e) {         logger.error("could not set default uncaught exception handler", e);     } }
