Intro and basic implementation. first up, you're going to need at least a urlstreamhandler. this will actually open the connection to a given url. So basically two methods named: getresource () and getresourceasstream () are used to load the resources from the classpath. these methods generally return the url’s and input streams respectively. these methods are present in the java.lang.class package. so here we are taking getting absolute classpath using classloader () method. Here is from doc api: before delegation, an absolute resource name is constructed from the given resource name using this algorithm: if the name begins with a ' ' ('\u002f'), then the absolute name of the resource is the portion of the name following the ' '. Here, input.txt is at the root directory of the jar. so when the code executes, we'll see the filenotfoundexception. even if we changed the path to input.txt the original code could not load this file as resources are not usually addressable as files on disk. the resource files are packaged inside the jar and so we need a different way of.

The short answer. the short answer is that you use these java command line parameters to help control the ram use of application: use xmx to specify the maximum heap size. use xms to specify the initial java heap size. use xss to set the java thread stack size. use this syntax to specify the amount of memory the jvm should use:.
