To avoid hard coding you can read the size of the array from the user using command line arguments of the reader classes like Scanner. Then using this value create an array:Exampleimport java.util.Arrays; import java.util.Scanner; public class PopulatingAnArray { public static void main(String args[]) { System.out.println("Enter the required size of the array :: "); Scanner s = new Scanner(System.in); int size = s.nextInt(); int myArray[] = new int [size]; System.out.println("Enter the elements of the array one by one "); for(int i=0; i

Read MoreBinding OData service to SAP UI5 table
Your service end point is incorrect- var oModel = new sap.ui.model.odata.v2.ODataModel("http://admin- think:88/sap/...",{useBatch : true});.To fix this issue, you need to remove “CoreOpenAppSet()” portion of the variable which is getting passed to ODataModel constructor. You need to pass function import using ODataModel- “oModel.callFunction()”.Once function call is completed, you can bind the result using “setBindingContext” as in below code −var oPromise = oModel.callFunction("/CoreOpenAppSet"); oPromise.contextCreated().then(function(oContext) { oView.setBindingContext(oContext); });
Read MoreHow can we create a MySQL stored function that uses the dynamic data from a table?
MySQL Stored functions can reference tables but they cannot make use of statements that return a result set. Hence we can say that there is no SELECT query that returns result set. But we can have SELECT INTO to get rid of that. For example, we are creating a function ‘Avg_marks’ that uses the dynamic data from table named ‘Student_marks’, having following records, to calculate the average of marks.mysql> Select * from Student_marks; +-------+------+---------+---------+---------+ | Name | Math | English | Science | History | +-------+------+---------+---------+---------+ | Raman | 95 | 89 | 85 | ...
Read MoreHow to use sub-package in Java?
Subpackages are similar to sub-directories. Consider an example. The company had a com.apple.computers package that contained a Dell.java source file, it would be contained in a series of subdirectories like this −....\com\apple\computers\Dell.javaAt the time of compilation, the compiler creates a different output file for each class, interface, and enumeration defined in it. The base name of the output file is the name of the type, and its extension is .class.For example −// File Name:Dell.java package com.apple.computers; public class Dell { } class Ups { }Now, compile this file as follows using -d option −$javac -d.Dell.javaThe files will be compiled as ...
Read MoreHow can we import only specific columns from the text file, into MySQL table?
Suppose if we have the values for some specific columns in the text file and MySQL table, in which we want to import the data, is having an extra column(s) then by mentioning the names of the columns in the query we can upload the values of those specific columns only. It can be understood with the help of the following example −ExampleSuppose we are having the values of columns ‘id’, ‘Name’ and ‘Salary’ only in the text file as follows −105, Chum, 11000 106, Danny, 12000Now while importing this text file into MySQL table then we need to mention ...
