Java text to ASCII converter with a loop

I'm trying to my first program text to ASCII converter, but I have some problems, it's explained inside the code:

import java.util.Scanner;

public class AsciiConverter {

    public static void main(String[] args){
        System.out.println("Write some text here");
        Scanner scanner = new Scanner(System.in).useDelimiter("\\n"); // Scans whole text
        String myChars = scanner.next();
        int lenght = myChars.length(); // Checking length of text to use it as "while" ending value  
        int i = -1;
        int j = 0;
        do{
            String convert = myChars.substring(i++,j++); // taking first char, should be (0,1)...(1,2)... etc 
            int ascii = ('convert'/1); // I'm trying to do this, so it will show ascii code instead of letter, error: invalid character constant
            System.out.print(ascii); // Should convert all text to ascii symbols
        }
        while(j < lenght );
        scanner.close();
    }
}

(Maybe use Scanner.nextLine().)

import java.text.Normalizer;
import java.text.Normalizer.Form;
String ascii = Normalizer.normalize(myChars, Form.NFKD)
        .replaceAll("\\P{ASCII}", "");

This splits all accented chars like ĉ into c and a zero length ^. And then all non-ascii (capital P = non-P) is removed.

String x = "text"; // your scan text
for(int i =0; i< x.getLength(); x++){
    System.out.println((int)x.charAt(i)); // A = 65, B = 66...etc...
}

This code will work

import java.util.Scanner;

public class AsciiConverter {

public static void main(String[] args){
    System.out.println("Write some text here");
    Scanner scanner = new Scanner(System.in).useDelimiter("\\n"); // Scans whole text
    String myChars = scanner.next();
    int lenght = myChars.length(); // Checking length of text to use it as "while" ending value  
    int i = -1;
    int j = 0;
    do{
        String convert = myChars.substring(i++,j++); // taking first char, should be (0,1)...(1,2)... etc 
        int ascii= (int)convert; // I'm trying to do this, so it will show ascii code instead of letter, error: invalid character constant
        System.out.print(ascii); // Should convert all text to ascii symbols
    }
    while(j < lenght );
    scanner.close();
}
}

did you missed type casting the character to integer? try this: 

int ascii = (int) convert;

Replace this line 

"int ascii = ('convert'/1);"

by

int ascii= (int)convert;

This should work.

Try this:

    public static void main(String[] args){
        System.out.println("Write some text here");
        Scanner scanner = new Scanner(System.in).useDelimiter("\\n"); // Scans whole text
        String myChars = scanner.next();
        char[] charArray = myChars.toCharArray();
        for (char character : charArray) {
            System.out.println((int)character);
        }
        scanner.close();
    }

This converts the string to a char array and then prints out the string representation of each character.
