We can verify whether the given string is empty using the isEmpty() method of the String class. This method returns true only if length() is 0.Example Live Demoimport java.lang.*; public class StringDemo { public static void main(String[] args) { String str = "tutorialspoint"; // prints length of string System.out.println("length of string = " + str.length()); // checks if the string is empty or not System.out.println("is this string empty? = " + str.isEmpty()); } }Outputlength of string = 14 is this string empty? = false
In SAP HANA database, you have different system schema. _SYS_BIC schema in SAP HANA database is used to store column views of all the activated objects in HANA repository. When an object is created and activated (HANA Modeling views, Stored Procedures), run time objects are saved under _SYS_BIC/Column views in database.These column views are used by front-end tools like BusinessObjects to get the data in a query.
JavaScript goto statement is a reserved keyword. Generally, according to web standards it isn’t considered a good practice to use goto statement.Using goto with JavaScript preprocessing is still considered good as shown below.var a = 0; [lbl] beginning: console.log("Demo Text!"); a++; if(i < 424) goto beginning;The above code gets translated like the following −var a = 0; beginning: while(true) { console.log("Demo Text!"); a++; if(i < 424) continue beginning; break; }
The parseXxx() method is used to get the primitive data type of a certain String. In this case to convert a String to integer you could use the parseInt() method.Example Live Demopublic class Test { public static void main(String args[]) { int x =Integer.parseInt("9"); double c = Double.parseDouble("5"); int b = Integer.parseInt("444",16); System.out.println(x); System.out.println(c); System.out.println(b); } }Output9 5.0 1092
The charAt() method of the String class returns the char value at the specified index. An index ranges from 0 to length() - 1. The first char value of the sequence is at index 0, the next at index 1, and so on, as for array indexing.The indexOf(int ch, int fromIndex) method of the String class returns the index within this string of the first occurrence of the specified character, starting the search at the specified index.If a character with value ch occurs in the character sequence represented by this String object at an index no smaller than fromIndex, then the index of ...

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
PHP uses a mysql_query function to create a MySQL table. This function takes two parameters and returns TRUE on success or FALSE on failure. Its syntax is as follows − Syntax bool mysql_query( sql, connection ); Followings are the parameters used in this function − Sr.No Parameter & Description 1 Sql Required - SQL query to create a MySQL table 2 connection Optional - if not specified, then the last opened connection by mysql_connect will be used.
I would recommend generateDS for converting a XSD file to a Python class . In my opinion, it is a good tool for the said purpose.It (generatS) generates the Python class with all methods (setters and getters, export to XML, import from XML). It does a good job and works very well !.
