LESSON 5: JAVA MATH: ⚜️The Java Math class has many methods that allows you to perform mathematical tasks on numbers. ✳️The Math.sqrt(x) method returns the square root of x. ✳️The Math.max(x,y) method can be used to find the highest value of x and y. ✳️ The Math.abs(x) method returns the absolute (positive) value of x. ❤️ Math.random() returns a random number between 0.0 (inclusive), and 1.0 (exclusive). public class Firsta { public static void main(String[] args) { double x,y,z; /*double x = 3.14; double y = 3.41; double z = Math.max(x, y); double a = Math.sqrt(5); double ab = Math.ceil(x);// maximum number double ac = Math.floor(y);// minimum number System.out.println(z);*/ System.out.println(z); System.out.println(z);

LESSON 5: JAVA MATH public class Firsta { public static void main(String[] args) { double x,y,z; /*double x = 3.14; double y = 3.41; double z = Math.max(x, y); double a = Math.sqrt(5); double ab = Math.ceil(x); double ac = Math.floor(y); System.out.println(z);*/

LESSON 4: IMPORTING SCANNER CLASS IN | JAVA 👨🏽‍💻Scanner is a class in java.util package used for obtaining the input of the primitive types like int, double, etc. and strings. ✳️To read numerical values of a certain data type XYZ, the function to use is nextXYZ(). ✅ 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) function returns the first character in that string. import java.util.Scanner; public class Firsta { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println("enter some String"); String name = scanner.nextLine(); System.out.println("enter your age"); int x = scanner.nextInt(); scanner.nextLine(); System.out.println("what is you departent? "); String dep =scanner.nextLine(); System.out.println("your name is: "+name); System.out.println("your age is:"+ x); System.out.println("your in "+dep+" departement now!"); } } » share and join this channel and » GROUP To cONTRIBUTE YOUR SKILL

LESSON 3 ASSIGNMENT ✅> Every variables is assigned data type that designates the type and quantity of value it can hold. ✳️<> as many of you guess , variable is a name given to a memory location. ⚜️During declaration of a variable, we nedd to take care of two things 1. Dataype 2. Dataname Similarly , we can initialize variables by assigning values in two ways: 1.variable initialization// 2. Assigning value by taking input from user// /look the snippet code below with different dataypes and initializations

public class Firsta {

  public static void main(String[] args) {
    long x = 2345267;
    float y =3.45f;
    boolean z = true;
    char ch = '@';
    String str ="learn to code!!";
        
    
        
    
    System.out.println("the number is: " +x);
    System.out.println(y);
      System.out.println(z);
      System.out.println(ch);
      System.out.println(str);

Error handling during file operations in C/C++ ✅It is quite common that errors may occur while reading data from a file in C++ or writing data to a file. Below are some Error handling functions during file operations in C/C++: ferror(): ❤️The ferror() function checks for any error in the stream. It returns a value zero if no error has occurred and a non-zero value if there is an error. »sample code: https://t.me/learntocodecpp/454 clearerr(): 🖤The function clearerr() is used to clear the end-of-file and error indicators for the stream. »sample code: https://t.me/learntocodecpp/457 The function perror() 🤍stands for print error. In case of an error, the programmer can determine the type of error that has occurred using the perror() function. »sample : https://t.me/learntocodecpp/458
