Java Program Removes Duplicate Characters from String

💻 Java Programming Practice – Count Vowels in a String. Today I practiced a Java program to count vowels in a string. 📌 What this program does: • Takes a string input from the user • Checks each character in the string • Identifies vowels (a, e, i, o, u) • Counts the total number of vowels ✅ Example: Input: RamanathapuramEducation Output: Vowels in the String = 10 💡 Concepts used in this program: ✔ Java Scanner input ✔ String methods ✔ For loop ✔ Conditional statements I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #Learning #SoftwareDevelopment

💻 Java Programming Practice – Reverse a String. Today I practiced a Java program to reverse a string. 📌 What this program does: • Takes a string input from the user • Reads each character from the end of the string • Builds a new reversed string • Displays the reversed output ✅ Example: Input: Tiruvannamalai Output: ialamannavuriT 💡 Concepts used in this program: ✔ Java Scanner input ✔ String length method ✔ For loop ✔ Character handling I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #Learning #SoftwareDevelopment

💻 Java Programming Practice – Count Repeated Character. Today I practiced a Java program to count how many times a character appears in a string. 📌 What this program does: • Takes a string input from the user • Takes a character to check • Compares the character with each letter in the string • Counts how many times the character appears ✅ Example: String: saravanan Character: a Output: Repeated character count = 4 💡 Concepts used in this program: ✔ Java Scanner input ✔ String methods ✔ For loop ✔ Character comparison I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #Learning #SoftwareDevelopment

💻 Java Programming Practice – Decimal to Binary Conversion. Today I practiced a Java program to convert a Decimal number into a Binary number. 📌 What this program does: • Takes a decimal number as input from the user • Uses division by 2 logic to find binary digits • Stores the values in an array • Prints the binary number as output ✅ Example: Decimal Number: 12 Binary Number: 1100 💡 Concepts used in this program: ✔ Java input using Scanner ✔ While loop ✔ Arrays ✔ Number conversion logic I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #LearningJourney #SoftwareDevelopment

💻 Java Programming Practice – Capitalize First Letter of Each Word. Today I practiced a Java program to capitalize the first letter of each word in a sentence. 📌 What this program does: • Takes a sentence input from the user • Splits the sentence into individual words • Converts the first character of each word to uppercase • Displays the updated sentence ✅ Example: Input: good morning Output: Good Morning 💡 Concepts used in this program: ✔ Java Scanner input ✔ String split() method ✔ Character array conversion ✔ Loops and conditions I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #Learning #SoftwareDevelopment

💻 Java Programming Practice – Find the Largest Word in a Sentence. Today I practiced a Java program to find the largest word in a sentence. 📌 What this program does: • Takes a sentence input from the user • Splits the sentence into individual words • Compares the length of each word • Displays the largest word in the sentence ✅ Example: Sentence: I am Dinesh from Tiruvannamalai Output: Largest word in the sentence = Tiruvannamalai 💡 Concepts used in this program: ✔ Java Scanner input ✔ String split() method ✔ Loops ✔ String length comparison I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #Learning #SoftwareDevelopment

💻 Java Programming Practice – Count Vowels and Consonants. Today I practiced a Java program to count vowels and consonants in a string. 📌 What this program does: • Takes a string input from the user • Checks each character in the string • Identifies vowels (a, e, i, o, u) • Counts both vowels and consonants ✅ Example: Input: RamanathapuramEducation Vowels in the String = 10 Consonants in the String = 13 💡 Concepts used in this program: ✔ Java Scanner input ✔ String methods ✔ For loop ✔ Conditional statements I am practicing Java programs daily to improve my coding and problem-solving skills for IT placements. #Java #Programming #CodingPractice #JavaDeveloper #Learning #SoftwareDevelopment

Java#P1 📌 Java Learning: How to remove duplicate characters from a string 👇 public class Remove Duplicates { public static void main(String[] args) { String str="programming"; String result=""; for (char ch : str.toCharArray()) { if (result.indexOf(ch) ==-1) { result+=ch; } } System.out.println("Original String: "+str); System.out.println("After removing duplicates: "+result); } } } 🧾 Output Original String: programming After removing duplicates: progamin 💡 indexOf() returns -1 → character not present Simple logic, but very useful in interviews. #Java #Coding #SDET #LearningInPublic
