Can't enter in this if-else statement

import java.util.Scanner;

public class ProgrammaD{
    public static void main(String[] args){
        Scanner keyboard= new Scanner(System.in);
        String sequence = args[0];
        char chars[] = new char[sequence.length()];

        for(int i = 0; i < sequence.length(); i++){
            chars[i] = sequence.charAt(i);
        }

        System.out.println("Insert a character");
        char car = keyboard.next().charAt(0);
        System.out.println("Insert an integer");
        int n = keyboard.nextInt();
        System.out.println("Original Array");

        for(int z = 0; z < sequence.length(); z++){
            System.out.println(chars[z]);
        }

        char chars2[] = MetodiD.occorrenzeContenuto(chars, n, car);
        System.out.println("Edited Array");

        for(int k = 0; k < sequence.length(); k++){
            System.out.println(chars2[k]);
        }

        boolean condition = false;
        char chars3[] = MetodiD.uniformaContenuto(chars, chars2);

        for(int x = 0; x < sequence.length(); x++){
            if(chars[x] == chars2[x]){
                condition = false;
            }
            else{
                condition = true;
            }
        }

        if(condition){
            for(int y = 0; y < sequence.length(); y++){
                System.out.println(chars3[y]);
            }
        }
    }
}

I can't execute the last if instruction, and I can't understand why. Could someone help me how to figure it out? I want the program to print the array returned in MetodiD.uniformaContenuto(), but I can't get anything from this code.
