here is the solution for the last part : Stringbuffer's equals() is not overridden. It does not compare values, it only compares reference value assignments. That is why you are getting false as they both are referring to different objects.
content.tostring()

plaindrome check ki constrructor use kora jai? gele ki vaba korbo?

last er problem ta jante parlam na.. video cut hoye gese

[robimojumdar]

if you don't mind, i have a question. when we use "equals ()" i.s equals methode, must be both will be string type?? Because of this video, when we compare string type and stringBuffer type then equals method are not work correctly.

If a user input "Madam" then it shows not palindrome... I think case matter... how can I check then?

vaia last a not palindrome dilo kno? sb==s1 reason ta bolar agei video cut hoa gese!

[ismailhossain]

package string_package;


public class PalindromeDemo {
public static void main(String[] args) {

String s1 = "121";

StringBuffer sb = new StringBuffer(s1);

sb.reverse().toString();
if(s1.equals(sb)){
System.out.println("Not Palindrome");
}else{

}




}

}
last second solution

last e keno not pallindrome aslo seta to bola holo na bhaia

[tanim]

package allstrings;

import java.util.Scanner;

public class PalindromeString {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

StringBuffer ch = new StringBuffer ();

System.out.println("Enter a String :");
ch.append(in.nextLine());

String b = ch.toString();
System.out.println("Before Reverse : ");
System.out.println(b);
ch.reverse();
System.out.println("After Reverse : ");
String c = ch.toString();
System.out.println(c);

if (b.equals(c)){
System.out.println(b+" is a palindrome word : "+b.equals(c));
}
else System.out.println(b+" is a palindrome word : "+b.equals(c);

}

}
easier understandable way

String sb = s2.reverse().toString();
System.out.print("After Reverse : "+sb);

System.out.println("");
if (s1.equals(sb)){

}else{

System.out.print("Not Plindrome ");
}
}

int length = str.length();

for ( int i = length-1; i >= 0; i-- )

if (str.equals(rev))
System.out.println(str+" is a palindrome");
else

}

How is this ?

import java.util.Scanner;

public class String_Palindrom {

public static void main(String[] args) {
try (Scanner input = new Scanner(System.in)) {
System.out.print("Enter a string : ");
String str = input.nextLine();
StringBuffer sb = new StringBuffer(str);

? "The string " + str + " is a string palindrome"
: "The string " + str + " is not a string palindrome");

}

}

}
