Java 字符串转换

Java数据类型教程 - Java字符串转换

String类有一个重载的valueOf()静态方法来获取任何原始数据类型或任何对象的值的字符串表示。例如，

public class Main {
  public static void main(String[] args) {
    String s1 = String.valueOf("C"); // s1 has "C"
    String s2 = String.valueOf("10"); // s2 has "10"
    String s3 = String.valueOf(true); // s3 has "true"
    String s4 = String.valueOf(2014); // s4 has "2014"
  }
}
