sample.java

    public static void main(String[] args) {
        String str = "abc";
        char ch[] = str.toCharArray();
        System.out.println("ch[0] = " + ch[0]);
        System.out.println("ch[1] = " + ch[1]);
        System.out.println("ch[2] = " + ch[2]);
    }

実行結果

ch[0] = a
ch[1] = b
ch[2] = c
