Convert input string into Uppercase

Convert Input string into Uppercase

 There are many built-in classes in the Java programming language. 'String', 'Scanner', 'Math' are some of out of all the built-in classes inside the Java programming language. And here you need 'String' class to convert the input string into Uppercase which is present inside the 'lang' package of the 'java' project.
All the built-in classes in Java contain many methods which are helpful to perform the mentioned specific task. So to convert the inputted string into uppercase you need to call toUpperCase() method from the String class. And is done by the keyword called  'import'.

import java.lang.String; //Importing String class from lang package
import java.util.Scanner; //Importing Scanner class from util package

public class StringToUC
{
    public static void main(String []args)
    {
         String str1; //Declaring Variables

          System.out.println("Enter String"); //Instruction to user to input string
         str1= new Scanner(System.in).nextLine(); //Getting string from keyboard

          String str=str1.toUpperCase(); //Processing value to UpperCase 
         System.out.println("The String in uppercase is "+str); //Printing Result
    }
 }


 Output of this program looks like this

 Enter String
qwerty The String in uppercase is QWERTY

Java program using Scanner Class

Scanner Class in Java The scanner is a class in java.util package used for obtaining the input of the primitive types like int, double, etc. and strings. It is the easiest way to read input in a Java program, though not very efficient if you want an input method for scenarios where time is a constraint like in competitive programming. To create an object of Scanner class, we usually pass the predefined object System.in, which represents the standard input stream. We may pass an object of class File if we want to read input from a file. To read the numerical values of a certain data type XYZ, the function to use is nextXYZ(). For example, to read a value of type short, we can use nextShort() To read strings, we use nextLine(). To read a single character, we use next().charAt(0). next() function returns the next token/word in the input as a string and charAt(0) funtion returns the first character in that string Program to calculate import java.util.Scanner; //Calli...

Calculate the area of Rectangle Using Constructor Overloading rules

Example of Constructor Overloading in Java program This is a java program to calculate the area of Triangle. This program is helpful to understand the constructor overloading. Here many constructors are called with the same name as same as of the class name 'Rectangle'. public class Rectangle { //Declaring global variables int length; int breadth; double area; Declaring global variables is accessible from wherever you want. Here many constructors are called and they need to be stored in the same variable so the global variables are created. The variables ' length ', ' breadth ', and ' area'  stores the length breadth and the area of the rectangle respectively.       public  Rectangle()  //Non-Parameterised Constructor     {           this. length=4;           this. breadth=2;     } The constructors with no any parameters are called...
