Java and JavaScript Lab Experiments: Classes, Inheritance, JSP and DOM

Experiment 1: Classes, Objects, Looping, and Branching in Java

Aim: To write a Java program demonstrating classes, objects, looping, and branching statements.

Code:

class Calculator {
int add(int a, int b) {
return a + b;
}
}
public class Exp1 {
public static void main(String[] args) {
Calculator calc = new Calculator();
// Branching (if-else)
int num = 10;
if (num > 0) {
System.out.println(num + ” is positive.”);
} else {
System.

Imagist Poetry and Modernist Works: Analysis of Key Poems

In a Station of the Metro – Ezra Pound

In this ultra-brief two-line poem, Ezra Pound captures a fleeting moment of urban beauty through Imagism, valuing visual precision and economical language. The primary technique is juxtaposition: human faces in the crowded metro are implicitly compared to “Petals on a wet, black bough”, suggesting delicacy and creating a contrasting atmospheric backdrop with the dark urban environment.

Words like “apparition” give a sense of sudden revelation, while

Forensic DNA Analysis and CRISPR Systems: Key Concepts

1) Chelex Extraction Steps

1. Hydration: Submerge the biological stain in sterile water at room temperature for 30 minutes to soften the sample matrix.
2. Debris Removal: Spin down the mixture via centrifugation and discard the substrate carrier (e.g., fabric or swab fragment).
3. Reagent Addition: Introduce the ion-exchange resin (Chelex) along with Dithiothreitol (DTT) and Proteinase K to the remaining cellular pellet.
4. Lysis Incubation: Maintain at 56°C to enzymatically digest cell membranes and

Its main advantages are fairness, consistency and predictability. However, it can be too rigid and ignore important circumstances.

Particularism means that personal
