 See how it runs with **pncrun** for each compiler. \\
+**Command Line Arguments:**\\
+Just a friendly reminder that when command line arguments are passed they are usually (I don't know of any cases when they aren't actually) passed as strings. Make sure to cast it from a string to whichever data type it is supposed to be.

+To do it in Java:
+<code>
+long startTime = System.nanoTime();
+.....your program....
+long endTime   = System.nanoTime();
+long totalTime = endTime - startTime;
+System.out.println(totalTime);
+</code>
+(You can change the output format as this will give you nano seconds)
+Or if you don't want to deal with nanoseconds you can use "System.currentTimeMillis()" instead
+**How to compile and run a java program in the terminal**\\
+Because compiling a java program will cause memory issues, some boundaries are needed to compile the program:
+<code>
+javac -J-XX:MaxHeapSize=512M -J-XX:InitialHeapSize=256M
+-J-XX:CompressedClassSpaceSize=128M -J-XX:MaxMetaspaceSize=128m -J-XX:MetaspaceSize=64m primeregbs.java
+</code>
+To run the program:
+<code>
+export CLASSPATH=${HOME}/src/comporg/pnc1/java
+java -XX:MaxHeapSize=512M -XX:InitialHeapSize=256M -XX:CompressedClassSpaceSize=128M -XX:MaxMetaspaceSize=128m -XX:MetaspaceSize=64m primeregbs ${*}
+</code>
+To display the time in Bash:
+<code>
+startTime=`date +%s%N`
+-Pnc1 code-
+endTime=`date +%s%N`
+totalTime=`bc <<< "scale=5; ${endTime} - ${startTime}"`
+totalTime=`bc <<< "scale=4; ${totalTime} / 1000000000"`
+echo "$totalTime"
+</code>
+JavaScript:
+The wrapper is as follows:
+<code>
+#!/bin/bash
+##
+## Wrapper for nodejs script
+##
+nodejs ${0}.js ${*}
+exit 0
+</code>
+To do timing in JavaScript:
+<code>
+var start = new Date().getTime();
+-Pnc1 code-
+var end = new Date().getTime();
+var time = (end-start)/1000;
+console.log(time);
+</code>
