1.Write a program for reverse String?

public class ReverseString {
    public static void main(String[] args) {
        String original = "Hello, world!";
        String reversed = "";

        for (int i = original.length() - 1; i >= 0; i--) {
            reversed += original.charAt(i);
        }

        System.out.println("Original string: " + original);
        System.out.println("Reversed string: " + reversed);
    }
}

package arithmeticOperations;

import java.lang.*;
import java.util.Scanner;

public class AreaOfTringle {
	
public static void main(String[] args) {
	
	float base, height,area;
	
	System.out.println("Enter base and height ");
	
	Scanner sc = new Scanner(System.in);
	base = sc.nextFloat();
	height =sc.nextFloat();
	
	area = 1f/2f* base * height ;
	
	System.out.println("Area of tringle " + area);
}
}

3. Write a program for Quadratic Equations

package arithmeticOperations;

import java.util.Scanner;

public class QuadraricEquations {
public static void main(String[] args) {
	int a,b,c;
	double r1, r2;

	System.out.println("Enter the value of a, b, c ");
	
	a=sc.nextInt();
	b=sc.nextInt();
	c=sc.nextInt();
	
	r1=(-b+Math.sqrt(b*b-4*a*c))/(2*a);
	r2=(-b-Math.sqrt(b*b-4*a*c))/(2*a);
	
	System.out.println("Root of " + r1 +"  "+ r2);
	
}
}

4. Write a program for Cuboid

package arithmeticOperations;

public class AreaAndVolumeOFCuboid {
public static void main(String[] args) {
	
	Scanner sc = new Scanner(System.in);
	
	int length, breath, height;
	
	System.out.println("Enter the value of Length, Breath, Height ");
	
	length = sc.nextInt();
	breath =sc.nextInt();
	height =sc.nextInt();
	
	int TotalArea, Volume;
	
	TotalArea=2*(length*breath+length*height+breath*height);
	Volume = length * breath * height ;
	
	System.out.println("Total area :" + TotalArea + " " + "Total Volume :"+ Volume);
}
}

5. Remove Special characters from String

package allPractisePrograms;

public class RemoveSpecialCharaFromString {
public static void main(String[] args) {
	
	String sample="ABCD!@#ABCD";
		
	System.out.println(sample.replaceAll("[^a-zA-Z0-9]", ""));
	
	String ExtraSpace = "dsaa s  sa         a  a  a                s da ds   s";
	
	System.out.println(ExtraSpace.replaceAll("\\s*", " "));
	
	String countWords="asdas  asfasf  asfsafsfa";
	
	String [] words=countWords.split("\\s");
	
	System.out.println(words.length);
}
}

6. Validate Email name and Domain name

package allPractisePrograms;

public class ValidateEmail {
public static void main(String[] args) {
	String mail= "user@gmail.com";
	
	int i= mail.indexOf("@");
	
	String user=mail.substring(0,i);
	String domain=mail.substring(i,mail.length());
	
	System.out.println(user + " + " + domain);
	System.out.println(domain.startsWith("@gmail"));
	System.out.println(domain.endsWith("com"));
	
}
}

7. Validate Binary Number

package allPractisePrograms;

public class ValidateBinaryNumber {
public static void main(String[] args) {
	int a =101011;
	String b=String.valueOf(a);
	
	System.out.println(b.matches("[01]*"));
	
	String Hexadecimal ="234AB";
	System.out.println(Hexadecimal.matches("[0-9A-F]*"));

}
}

8. Find Even/ Odd Number from given Value

package allPractisePrograms;
import java.util.*;
public class FindNumberEvenOrOdd {
public static void main(String[] args) {
	
	int n;
	Scanner sc = new Scanner(System.in);
	n= sc.nextInt();
	
	if (n%2==0) {
		System.out.println("This number id Even" + n);
	}
	else {
		System.out.println("This number is Odd " + n);
	}
}
}
