To set the width of an element’s border in JavaScript, use the borderWidth property. Set the width using this property. You can try to run the following code to learn how to set the width of an element’s border − Example Live Demo #box { border: thick solid gray; width: 300px; height: 200px } Demo Text Change border width function display() { document.getElementById("box").style.borderWidth = "thin"; }
The listIterator(int index) method of the java.util.LinkedList class returns a list-iterator of the elements in this list (in proper sequence), starting at the specified position in the list. Example import java.util.*; public class LinkedListDemo { public static void main(String[] args) { LinkedList list = new LinkedList(); list.add("Hello"); list.add(2); list.add("Chocolate"); list.add("10"); System.out.println("LinkedList:" + list); Iterator x = list.listIterator(1); while (x.hasNext()) { System.out.println(x.next()); } } } Output LinkedList:[Hello, 2, Chocolate, 10] 2 Chocolate 10
You can capitalize words in a string using the toUpperCase() method of the String class. This method converts the contents of the current string to Upper case letters.Example Live Demopublic class StringToUpperCaseEmp { public static void main(String[] args) { String str = "string abc touppercase "; String strUpper = str.toUpperCase(); System.out.println("Original String: " + str); System.out.println("String changed to upper case: " + strUpper); } }OutputOriginal String: string abc touppercase String changed to upper case: STRING ABC TOUPPERCASE

To find weather a string is rotation of another, concat the first string to itself twice and find weatherExample Live Demopublic class Sample { public static void main(String args[]){ String str1 = "gala"; String str2 = "alag"; String s3 = str1+str1; if(s3.contains(str2)) { System.out.println("str1 is rotation of str2"); } else { System.out.println("str1 is not rotation of str2"); } } }
Note that while modifying or creating the property configuration file, only the property which is different from default value needs to be set. The mistake in property configuration file may result in incorrect action or result of data source.

You can try to run the following code to learn how to work with filter() method in JavaScript − Example Live Demo JavaScript Array filter Method ... Read More
The add(E e) method of the java.util.ArrayList class appends the specified element E to the end of the list.Example:import java.util.ArrayList; public class ArrayListDemo { public static void main(String[] args) { ArrayList arrlist = new ArrayList(5); arrlist.add(15); arrlist.add(20); arrlist.add(25); for (Integer number : arrlist) { System.out.println("Number = " + number); } } }Output:Number = 15 Number = 20 Number = 25
