Widening Primitive Conversion in Java
Following is an example showing widening primitive conversion −Examplepublic class Demo { public static void main(String[] args) { System.out.print("H" + "E"); System.out.print('L'); System.out.print('L'); System.out.print('O'); } }OutputHELLOA class named Demo contains the main function. Here, the ‘print’ function is used to print specific characters in double quotes and then in single quotes. When the process of widening primitive conversion happens, the presence of ‘+’ operator is a must. This ‘+’ operator expects integer on both the left hand and right hand sides.

Let’s say we have an Octal number. To convert Octal to other bases like binary, hexadecimal, etc, the Java code is as follows −Examplepublic 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 from ...

To generate random numbers in a given range, the Java code is as follows −Exampleimport 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); System.out.println("The random values in the list are : "); for(int i=0; i
Read MorePrint Single and Multiple variables in Java
To print single and multiple variables in Java, the code is as follows −Examplepublic class Demo { public static void main(String args[]){ String name_1 = "Hello"; String name_2 = "World"; System.out.println("Printing single variable"); System.out.printf("%s", name_1); System.out.println("Printing multiple variables"); System.out.printf("First Name: %sLast Name: %s",name_1, name_2); } }OutputPrinting single variable Hello Printing multiple variables First Name: Hello Last Name: WorldA class named Demo contains the main function, which defines two strings. These strings are displayed using the ‘println’ function and using the ‘printf’ function.

For this, you need to use attr(). The attr() method can be used to either fetch the value of an attribute from the first element in the matched set or set attribute values onto all matched elements.Following is the JavaScript code −Example Document $('#myURL').attr('value', 'http://www.facebook.com'); To run the above program, just save the file name anyName.html(index.html) and right click on the file and select the option open with live server in VSCode Editor.OutputLook at the above sample output the URL has been changed from ...
