我有一个文本"abcdef“。我想打印"bcd“。你能给我一些方法吗？

text = "abcdef"
result = text[1:4]
print(result)

String text = "abcdef";
String result = text.substring(1, 4);
System.out.println(result);

var text = "abcdef";
var result = text.slice(1, 4);
console.log(result);

import re

text = "abcdef"
result = re.search("bcd", text).group()
print(result)

import java.util.regex.Matcher;
import java.util.regex.Pattern;

String text = "abcdef";
Pattern pattern = Pattern.compile("bcd");
Matcher matcher = pattern.matcher(text);
if (matcher.find()) {
    String result = matcher.group();
    System.out.println(result);
}

var text = "abcdef";
var result = text.match(/bcd/)[0];
console.log(result);

text = "abcdef"
result = text.replace("a", "").replace("f", "")
print(result)

String text = "abcdef";
String result = text.replace("a", "").replace("f", "");
System.out.println(result);

var text = "abcdef";
var result = text.replace("a", "").replace("f", "");
console.log(result);
