This document describes what you need to do in order to integrate your provider into Java SE so that algorithms and other services can be found when Java Security API clients request them.
Now there is no compilation error any more but when executing it, I find the raised SQLException still cannot be caught as I expect. My println is not executed at all. I have to catch the Exception, the super class of all other exception instead ( like CX_ROOT i...
This way the provider code to authenticate the JCE framework is executed only when the provider is run with JCE 1.2.2. The following is sample code:Class cipherCls = Class.forName("javax.crypto.Cipher"); CodeSource cs = cipherCls.getProtectionDomain().getCodeSource(); if (cs != null) {...
It will use jstack to capture a series of 6 thread dumps spaced 20 seconds apart (modify as needed), passing in the Java process ID as an argument. Make sure you setJAVA_HOMEin this script. It generates a file calledjstack_threaddump.outin the directory where this script is executed. Fo...
Profile your code:UseJava profilingtools to identify performance bottlenecks in your code. Profiling tools can provide detailed information about how your code is executed, including the time spent in each method and the number of times each method is called. Use this information to identify perform...
In most programming languages, when multiple conditions in the "else if" sequence are true, only the code block associated with the first true condition is executed. The program doesn't check the subsequent conditions once a true condition is found. ...
System.out.println("Wrong input type entered...exiting the program"); } } } In the above code, we have used atry-catchblock to catch the exception and then print a custom message to notify the user to enter a valid input. When the code above is executed, we get the following output...
What we do in practice is find a workaround for the problem: we assume the method is cold and compile it using the simple compiler and then execute the method a few times, let us say N. If the method is executed N times, we assume that it will execute at least N more times in ...
