Java 中的基本数据类型只有 8 个 :byte、short、int、long、float、double、char、boolean;除了基本类型(primitive type),剩下的都是引用类型(referencetype),Java 5 以后引入的枚举类型也算是一种比较特殊的引用类型。基本数据类型中用来描述文本数据的是char,但是它只能表示单个字符,比如 ‘a’,‘好’ 之类的,如...

In Java, you can use String.toCharArray() to convert a String into a char array. StringToCharArray.java package com.mkyong.utils; public class StringToCharArray { public static void main(String[] args) { String password = "password123"; char[] passwordInCharArray = password.toCharArray(); f...
Java String toCharArray() with example. The java string toCharArray() method converts the given string into a sequence of characters. Convert string to char. The returned array length is equal to the length of the string.
public class JavaStringToCharArray { public static void main(String[] args) { String str = "journaldev.com"; // get char at specific index char c = str.charAt(0); // Character array from String char[] charArray = str.toCharArray(); ...
In above program,toCharArrayandcharAtusage is very simple and clear. IngetCharsexample, first 7 characters of str will be copied to chars1 starting from its index 0. That’s all for converting string to char array and string to char java program. Reference:...
String类的toCharArray()public char[] toCharArray()将此字符串转换为一个新的字符数组。

但多了一层构造过程。对于将String转换为char，Java提供了更直接的方法：1. charAt()方法： `char c = s.charAt(index);` 可以获取字符串中指定位置的字符，index为0开始的索引。2. toCharArray()方法： `char[] charArray = s.toCharArray();` 将整个字符串转换为字符数组，方便访问每个字符。
