字符串 [] min 詳解 pro java true 常量 intern
class StringEqualTest {
public static void main(String[] args) {
String s1 = "Programming";//棧
String s2 = new String("Programming");//棧
String s3 = "Program";//常量
String s4 = "ming";//常量
String s5 = "Program" + "ming";//棧
String s6 = s3 + s4;//常量
System.out.println(s1 == s2);//false
System.out.println(s1 == s5);//
System.out.println(s1 == s6);
System.out.println(s1 == s6.intern());
System.out.println(s2 == s2.intern());//這句話等價於s2==s1當然是false
}
