Creating And Executing Threads In Java An Overview Of Extending The In java, == and the equals method are used for different purposes when comparing objects. here's a brief explanation of the difference between them along with examples: == operator: the == operator is used for reference comparison. it checks whether two references point to the exact same object in memory. example:. What is the percent % operator in java? asked 8 years, 2 months ago modified 4 years ago viewed 63k times.

Java Threads Tutorial Multithreading In Java Tutorial Java Tutorial Not only in java, this syntax is available within php, objective c too. in the following link it gives the following explanation, which is quiet good to understand it: a ternary operator is some operation operating on 3 inputs. it's a shortcut for an if else statement, and is also known as a conditional operator. in perl php it works as:. It is the bitwise xor operator in java which results 1 for different value of bit (ie 1 ^ 0 = 1) and 0 for same value of bit (ie 0 ^ 0 = 0) when a number is written in binary form. The diamond operator in java 7 allows code like the following: list list = new linkedlist<>(); however in java 5 6, i can simply write: list list = new linkedlist(); my understanding of type erasure is that these are exactly the same. (the generic gets removed at runtime anyway). why bother with the diamond at all? what new functionality type safety does it allow? if it doesn. The flag xmx specifies the maximum memory allocation pool for a java virtual machine (jvm), while xms specifies the initial memory allocation pool. this means that your jvm will be started with xms amount of memory and will be able to use a maximum of xmx amount of memory. for example, starting a jvm like below will start it with 256 mb of memory and will allow the process to use up to 2048 mb.

Java has 5 different boolean compare operators: &, &&, |, ||, ^ & and && are "and" operators, | and || "or" operators, ^ is "xor" the single ones will check every parameter, regardless of the values, before checking the values of the parameters. the double ones will first check the left parameter and its value and if true (||) or false (&&) leave the second one untouched. sound compilcated? an. 1 there won't be any difference in terms of performance. using java cp we can specify the required classes and jar's in the classpath for running a java class file. if it is a executable jar file . when java jar command is used, jvm finds the class that it needs to run from meta inf manifest.mf file inside the jar file. See the jar tool reference page and the jar trail of the java tutorial for information about working with jar files and jar file mani fests. when you use this option, the jar file is the source of all user classes, and other user class path settings are ignored. I was just reading this line: the first thing the format() method does is load a velocity template from the classpath named output.vm please explain what was meant by classpath in this context, a.
