如何比较两个字符串的值是否相等,最好的方法是什么？

public static boolean stringCompare(String s1, String s2) {
    char[] char1 = s1.toCharArray();
    char[] char2 = s2.toCharArray();
    return Arrays.equals(char1, char2);
}

public static boolean intCompare(String s1, String s2) {
    int int1 = Integer.parseInt(s1);
    int int2 = Integer.parseInt(s2);
    return int1 == int2;
}

public static boolean floatCompare(String s1, String s2) {
    float float1 = Float.parseFloat(s1);
    float float2 = Float.parseFloat(s2);
    return float1 == float2;
}

public static boolean regexCompare(String s1, String s2) {
    String regex = "\\d+";
    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(s1);
    if (matcher.find()) {
        return Integer.parseInt(s1) == Integer.parseInt(s2);
    }
    return false;
}

public static boolean characterCompare(String s1, String s2) {
    return s1.equals(s2);
}
