C++ Program for Convert String to Lower Case and Upper Case #include <iostream>using namespace std;void lowerString(string str){ for(int i=0;str[i]!='\0';i++) { if (str[i] >= 'A' && str[i] <= 'Z') //checking for uppercase characters str[i] = str[i] + 3 ..read more

In previous tutorial you learned about features of Java language but In this tutorial, We will provide justify of the feature Java Platform Independent. Our machine understand machine level language but it is not possible to write code in machine level language that's why we write code in human readable and then this source code is converted to machine level language. So, Computer can understand our instructions.  In C/C++ programming language the code is converted into machine language with the help of compilers and we get .exe file which is platform dependent and this m ..read more

In this example, You learn about Java program to find LCM of two numbers. Here you learn find LCM of numbers in Java, You are given two numbers and the task of the program to find LCM/GCD in Java. LCM(Lowest Common Factor) A Lowest Common Factor of two numbers is the smallest positive number that is divisible by both numbers. Example, LCM of 10 and 15 is 30 because 30 is the lowest number divisible by both 10 and 15. GCD(Greatest Common Divisor/Highest Common Factor) A Greatest Common Divisor of two numbers is the largest positive number and non zero numbers that is divisi ..read more

In this example, You learn about Java program for Pythagorean Triples.  Here you learn pythagorean triplet in Java, You are given a numbers and the task of the program to deduce whether the given numbers form a right angled triangle or not i.e. pythagorean triplet in Java. A Pythagorean Triples are the three positive integers a, b, and c such that a2 + b2 = c2. Here a id perpendicular, b is base and c is hypotenuse. Java Program for Pythagorean Triples import java.util.*;public class Main { public static void main(String[] args) { Scanner scn = new Scanner(System ..read more

In this example, You learn about Java program to remove spaces from string.  Here you learn Java remove spaces from string, You are given a string and the task of the program to remove spaces in Java. We use length() function to find a length of string and charAt() to find character at specific index.  To remove space we create new empty string and append each character from original string to this new string if find space ' ' then skip it to append (as space is treated as character). Then print the new string. Java Program to Remove Spaces from String import java.ut ..read more
