Thread: How to remove letters

how do you remove letters in a string?

Hello!
I'm new here, just sign up today! Hoping to make new friends!

this might help you a little bit

public class StringFormat3 {
 
    public static void main(String[] args) {
 
        String name;
 
        name = "zabdiel";
 
        //dont bother this part.. its only for measuring the lenght of a strings ,using .length() method.
        System.out.println("Your name consists of " + name.length() + " characters");
 
        //the following statements shows how to extract a character or a String in a String.
        System.out.println(name.substring(0,1));
        System.out.println(name.substring(1,2));
        System.out.println(name.substring(2,3));
        System.out.println(name.substring(3,4));
        System.out.println(name.substring(4,5));
        System.out.println(name.substring(5,6));
        System.out.println(name.substring(6,7));
    }
}

another example..

this one will show you how to extract or remove a String.
this one differs to my first example..

public class Sample1 {
 
    public static void main(String[] args) {
 
        String name = "Zabdiel";
 
        String extracted1,
               extracted2,
               extracted3;
 
        extracted1 = name.substring(1);
        extracted2 = name.substring(2);
        extracted3 = name.substring(3);
 
        System.out.println(extracted1);
        System.out.println(extracted2);
        System.out.println(extracted3);
    }
}

How about using a StringBuilder?

StringBuilder (Java Platform SE 6), int)

// Json

ei.. in string builder? extract a string? can you please give a little example of that using stringbuilder sir?
tnx in advance!!

How about this then.

        final StringBuilder stringBuilder = new StringBuilder("Please remove me");
        System.out.println(stringBuilder.toString());
 
        stringBuilder.delete(7, 14);
        System.out.println(stringBuilder.toString());

Output:

Please remove me
Please me

// Json

ahh .delete() method.. whaa didnt notice it

hmmm ill keep that one

delete is only available on the StringBuilder though I believe.

// Json

use BufferString class is a good idea.

how sir? can you show a little example?

for example:if you want remove letters "ge" from string "gehaiming",you could do like the follow code.

StringBuffer sb=new StringBuffer("gehaiming");
sb=sb.replace(0,2,"");
