HTML DOM UiEvent detail Property
The HTML DOM UiEvent detail property returns a number corresponding to clicks triggered continuously.NOTE − If ondblclick event is triggered returned value is ‘2’, and always ‘0’ if onmouseover or onmouseout event is triggered.SyntaxFollowing is the syntax −Returning number of clicks triggered continuously −event.detailLet us see an example of Event detail property −Example Live Demo HTML DOM UiEvent detail form { width:70%; margin: 0 auto; text-align: center; } * { padding: 2px; margin:5px; } input[type="button"] { ...

To generate random numbers in a given range, the Java code is as follows −Example Live Demoimport java.util.Random; import java.util.*; public class Demo{ public static void main(String args[]){ Random my_rand = new Random(); List my_list_1 = new ArrayList(); int v_1 = my_rand.nextInt(1000); int v_2 = my_rand.nextInt(967); int v_3 = my_rand.nextInt(1050); int v_4 = my_rand.nextInt(10000); int v_5 = my_rand.nextInt(100); my_list_1.add(v_1); my_list_1.add(v_2); my_list_1.add(v_3); my_list_1.add(v_4); my_list_1.add(v_5); ...
Read MoreConvert one base to other bases in a single Java Program
Let’s say we have an Octal number. To convert Octal to other bases like binary, hexadecimal, etc, the Java code is as follows −Example Live Demopublic class Demo{ public static String base_convert(String num, int source, int destination){ return Integer.toString(Integer.parseInt(num, source), destination); } public static void main(String[] args){ String my_num = "345"; int source = 8; int destination = 2; System.out.println("Converting the number from octal to binary: "+ base_convert (my_num, source, destination)); destination = 10; System.out.println("Converting the number ...
Read MoreHow to write an empty function in Java
Let us see how to write an empty function in Java −Example Live Demoimport java.util.Vector; public class Demo{ public static void my_empty_fun(){ } public static void main(String[] args){ System.out.println("In the main function"); my_empty_fun(); } }OutputIn the main functionAn empty function is basically creating a function without defining any operations inside it. A class named Demo contains an empty function named ‘my_empty_fun’ which is just completed by placing two flower brackets, without adding any functionality into it. In the main function, a print statement is written after which the empty function ...
Read MoreRun-time Stack mechanism in Java
Eeverytime a process or a code or a thread needs to run in Java, a runtime stack is created so as to store the operations performed while executing the thread.Every entry in the run-time stack is known as stack frame or activation record. Once a function has been called by the process, its associated data is deleted from the runtime stack.Once all the functions have been called, the runtime stack will be empty. This means it needs to be removed from the memory.At this point in time, the runtime stack is destroyed and then the thread is also terminated.A termination ...
