Why is it throwing an error? Any help would be appreciated

public class RAWS {public String rawsc(String ori){    String temp="";    for(int i=0;i<ori.length();i++)    {        char c=ori.charAt(i);        if(((c>=65)&&(c<=90))||((c>=97)&&(c<122)))            temp=c+temp;    }    for(int i=0;i<ori.length();i++)    {        char c=ori.charAt(i);        if(((c>=65)&&(c<=90))||((c>=97)&&(c<122)))            ori.replace(c, temp.charAt(i));    }    for(int i=0;i<ori.length();i++)    {        System.out.println(ori.charAt(i));    }    return(ori);}public static void main(String[] args) {    String str="a,b$c";    RAWS ob=new RAWS();    String new1=ob.rawsc(str);    for(int i=0;i<new1.length();i++)    {        System.out.print(new1.charAt(i)+" ");    }}}

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 4 at java.lang.String.charAt(String.java:658) at arraygs.RAWS.rawsc(RAWS.java:22) at arraygs.RAWS.main(RAWS.java:30)

The following prints out the entered sentence in order. I need it to print the input in reverse order:

import java.util.Scanner;public class Sentence {    public static void main(String [] args) {        Scanner input = new Scanner(System.in);        System.out.print("Enter a sentence: ");        String sentence = input.nextLine();        String[] tokens = sentence.split(" ");        System.out.println(tokens.length);        for (String token : tokens) {            System.out.println(token);        }       }}

I'm trying to implement a simple method in Ruby that takes a string as an argument, and returns the string in reverse.

def reverse word  reversed = word.reverse  puts word + ' reversed is ' + reversed + '.'end

I have created a basic C# with reverse a string.

public static void Main(){string name= "jackson";Console.WriteLine(name);string finalOutput = string.Empty;for(int i=1;i <= name.Length ;i++){finalOutput= finalOutput + name[name.Length-i];}Console.WriteLine(finalOutput);}

Output:jacksonnoskcaj

i'm new to assembly language and i am trying to figure this code:

org 100h.data    string db "miracle si elcarim $"    string2 db 13 dup(?)    count dw 18.codestart:  mov ax, @data        mov ds, ax        mov es, ax        mov cx, count        mov si, 0        mov di, 0        add di, count        dec diagain:  mov al, string[si]        mov string2[di], al        inc si        dec di        lea dx,string2        mov ah,9h        int 21h        jmp again        mov ah, 4ch        int 21hret

i am trying to reverse string into string2 by looping again and print out string2 at the end.

Please i need help!
