Java Tutorial: String Methods in Java

Love Harry bhai for notes.Amazingly written!

tomar pakhir naaam tuntuni

Thanks bro

Wonderful !!!!!!!!!!!!!!!!!!!!!!!!
Thank you

public class str_method {
public static void main(String args[]) {
String s = "Manjirian";
//string are immutable hence this method will not change original string insad it will return new string
System.out.println(s.length());//return int

System.out.println(s.toLowerCase());//return new string

System.out.println(s.toUpperCase());//return new str

String s2 = " hi ";

System.out.println(s2);

System.out.println(s2.trim()); //return new str

System.out.println(s.substring(1));//return new str

System.out.println(s.substring(1,4));

System.out.println(s.substring(0));

System.out.println(s.replace('a','&')); //return string
System.out.println(s.replace("a","&+*"));


System.out.println(s.startsWith("m"));//return boolean
System.out.println(s.endsWith("i"));

System.out.println(s.charAt(0));//give char at given index
System.out.println(s.indexOf("an"));//return index of given substring :start index
System.out.println(s.indexOf("an",4));//return index of given substring :fron specified index
System.out.println(s.indexOf("an000"));//return -1 if not found
System.out.println(s.lastIndexOf("an"));//start from last return last index
System.out.println(s.lastIndexOf("an",4));//start from last only search from 4 from last

System.out.println(s.equals("Manjirian"));//return boolean if string are equal or not
System.out.println(s.equalsIgnoreCase("ManjIRian"));//it will check without case sensitivity




}
}

just OP man like Just how..... Just How Can you make All this Explanation so easy........ oh my goddd!!!!

👍

Teaching great👍

thanku harry sir

❤❤

please reply me @codeWithHarry sir

our program is
public class String_methods {
public static void main(String[] args)
{
String name = "Shahid";
System.out.println(name);

// lenght()
int s = name.length();
System.out.println(s);

// toLowerCase()
String a = name.toLowerCase();
System.out.println(a);

// toUpperCase()
String b = name.toUpperCase();
System.out.println(b);

// trim()
String nontrimString =" Shahid Jamal " ;
System.out.println(nontrimString);
String trimString= nontrimString.trim();
System.out.println(trimString);

// Substring()
System.out.println(name.substring(3));
System.out.println(name.substring(1,4));

// replace()
System.out.println(name.replace('S','Z'));
System.out.println(name.replace("Sh",'Z'));
System.out.println(name.replace("Sha","Za"));
System.out.println(name.replace("h","Yee"));





}
}

In VS code
System.out.println(name.replace("Sh",'Z'));
System.out.println(name.replace("h","Yee"));
these statement are not Executed creating error
error is char cannot be converted to CharSequence

Thank You ❤️

Harry bhai notes ka link work nhi kar raha..... please help me

I am from non IT background but ur video is so helpful for me.... 😊so Thank u so much

import java.util.Scanner;
public class SumOfIntegers {
public static void main(String[] args) {

String str = "Dheeraaj" ;

// System.out.println(str.length());
// System.out.println(str.toLowerCase());
// System.out.println(str.toUpperCase());
// System.out.println(str.trim());
// System.out.println(str.substring(2));
// System.out.println(str.substring(3,6));
// System.out.println(str.replace('a','e'));
// System.out.println(str.replace("Dh", "tt"));
// System.out.println(str.startsWith("Dh"));
// System.out.println(str.endsWith("fg"));
// System.out.println(str.charAt(2));
// System.out.println(str.indexOf("e" , 4));
// System.out.println(str.lastIndexOf('a',5));
// System.out.println(str.equals("Dheeraaj"));
// System.out.println(str.equalsIgnoreCase("dhEEraaj"));
// System.out.println("I am \"beginner \" in programming");
// System.out.println("I am 'beginner'\\in programming");

Harry bhai before watching this video I was having a lot of doubt after watching this video all my doubts are solved thank you.

Harry bhai aap kon sa coding software ka use karta ho

you missed two important concept stringbuilder and stringbuffer

public class cwh_14_String_methods {
public static void main(String[] args) {
String name = "Sourav";
//System.out.println(name);
int value = name.length();
//System.out.println(value);

// String lowerstring = name.toLowerCase();
// System.out.println(lowerstring);
//
// String upperstring = name.toUpperCase();
// System.out.println(upperstring);
//
// String nontrimmedstring = " Sourav ";
// System.out.println(nontrimmedstring);
//
// String trimmedstring = nontrimmedstring.trim();
// System.out.println(trimmedstring);

// System.out.println(name.substring(2));
// System.out.println(name.substring(2,4));
//
// System.out.println(name.replace('v','b'));
// System.out.println(name.replace("v","bh"));
//
// System.out.println(name.startsWith("Sou"));
// System.out.println(name.endsWith("av"));

// System.out.println(name.charAt(1));

// String modifiedName = "soouravvv";
// System.out.println(modifiedName.indexOf("vvv"));
// System.out.println(modifiedName.indexOf("vvv", 2));
// System.out.println(modifiedName.lastIndexOf("vvv",7));
System.out.println(name.equals("SOURAV"));
System.out.println(name.equalsIgnoreCase("SouRav"));

System.out.println("I am escape sequence\\double quote");


}
}
