Given a string s consisting of words and spaces, return the length of the last word in the string. A word is a maximal substring consisting of non-space characters only. Example 1: Input: s = “Hello World” Output: 5 Explanation: The last word is “World” with length 5. Example 2: […]
In Java, a method can be defined with a return type and without arguments. This means the method returns a value but does not take any input parameters. ✅ General Syntax: returnType methodName() { // method body return value; // value must match returnType } In Java, methods can be categorized by whether they return […]
Write a program to minus two numbers without using minus operator int a=5;b=2,c; c=(a+(~b))+1 System.out.println(c); c=(a+(~b))+1 ==>(5+(-3))+1 ==>(5-3)+1 ==>(2)+1 =>3 import java.util.Scanner; public class SubtractWithoutMinus { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.print(“Enter first number (a): “); int a = sc.nextInt(); System.out.print(“Enter second number (b): “); int b = sc.nextInt(); […]
Bitwise Operators Operate on binary representations. Operator Description Example (a=5, b=3) & Bitwise AND a & b = 1 ` ` Bitwise OR ^ Bitwise XOR a ^ b = 6 ~ Bitwise NOT ~a << Left shift a << 1 = 10 >> Right shift a >> 1 = 2 int x=10,y=5; //10==>1010 […]
Java Reserved Keywords: Java has a set of keywords that are reserved words that cannot be used as variables, methods, classes, or any other identifiers. For example: break, char, double, final Literal: Any constant value which can be assigned to the variable is called literal/constant. Literals in Java is a synthetic representation of boolean, numeric, […]

The percentage of total literacy is 48. If total percentage of literate men is 35 of the total population, Write a program to find the total number of illiterate men and women if the population of the town […]
Here is a simple Java program to check whether a given letter is a vowel or a consonant. ✅ Java Code: import java.util.Scanner; public class VowelOrConsonant { public static void main(String[] args) { Scanner sc = new Scanner(System.in); // Input a character System.out.print(“Enter a letter: “); char ch = sc.next().charAt(0); // Convert to lowercase for […]
