java - 如何使用 Java 中的 stringreader 获取字符串中的下一个字符？

Question

考虑这段代码:

public static void main (String[] args) {

    String name = "(My name is Bob)(I like computers)"

    StringReader s = new StringReader(name);

    try {
        // This is the for loop that I don't know 
        for () {
            String result = "";  
            // Here the char has to be appended to the String result.
        }
        System.out.println("The string is: " + result);

    } catch (Exception e) {
        e.toString();
    }
}

我正在寻找的是一个 for 循环，它首先查看当前位置的字符，如果该字符不是“)”，则将其附加到字符串。但是，还应将字符“)”附加到字符串中。在此示例中，输出应为:

字符串结果是:(我叫鲍勃)

下面是一个可行的解决方案。

import java.io.StringReader;

public class Re {
public static void main (String[] args) {
String name = "(My name is Bob)(I like computers)";

StringReader s = new StringReader(name);

try {
    // This is the for loop that I don't know
    String result = "";
    int c = s.read();
    for (;c!= ')';) {
        result = result + (char)c;
        // Here the char has to be appended to the String result.
        c = s.read();
    }
    result = result + ')';
    System.out.println("The string is: " + result);

} catch (Exception e) {
    e.toString();
}

}
}
