Java char[]数组转成String类型详细介绍

public class Test {

    public static void main(String[] args) {
        char[] c = {'a','b','c','d'};
        char d= 'e';
        System.out.println("String is: "+ String.valueOf(c));//String is: abcd
        System.out.println("String is: "+ String.valueOf(d));//String is: e
        System.out.println("String is: "+ Character.toString(d)); //String is: e

    }
}

String is: abcd
String is: e
String is: e

public class Test {

    public static void main(String[] args) {
        char[] char = {'A','A','N','A','A','B'};
        String str = new String(char);
        System.out.println(str);//System.out.println(new String(char));

    }
}

public class Test3 {
    public static void main(String[] args) {
        char c = 'G';// 声明一个字符变量
        // 连接 char 变量
        // 使用空字符串
        String s = "" + c;

        // 打印并显示上面的字符串
        System.out.println("Char to String using Concatenation :"
                        + " " + s);
    }
}

Char to String using Concatenation : G

public class Test {

    public static void main(String[] args) {
        char d= 'e';// 声明一个字符变量
        String s = Character.toString(d);//使用 toString 将 char 转换为 Strin
        System.out.println("Char to String using Character.toString method :"
                + " " + s);

    }
}

Char to String using Character.toString method : e

public class Test {

    public static void main(String[] args) {
        char[] c = {'a','b','c'};
        Character ch= 'G';//或者 Character ch= new Character('G');
        String s = ch.toString();//使用 toString 将 char 转换为 String
        System.out.println("Char to String using toString method :"
                + " " + s);

    }
}

Char to String using toString method : G

public class Test {

    public static void main(String[] args) {
        char[] c = {'a','b','c'};
        Character ch= 'G';
        //通过以下方式将 char 转换为 String
        //使用 String.valueOf() 方法
        String s = String.valueOf(new char[]{ch});
        System.out.println(
                "Char to String using String.valueOf(new char[]) method :"
                        + " " + s);

    }
}

Char to String using String.valueOf(new char[]) method : G
