String及String的内存分析

public class TestString {

//String:代表不可变的字符序列。底层使用char[]存放。
//String是final的
@Test
public void test1(){
String str1 = "JavaEE";
String str2 = "JavaEE";
String str3 = new String("JavaEE");
String str4 = "JavaEE" + "Android";
String str5 = "Android";
String str6 = str1 + str5;
str5 = str5 + "Handoop";
String str7 = str6.intern();
String str8 = "AndroidHandoop";

System.out.println(str1 == str2);//true
System.out.println(str1 == str3);//false
System.out.println(str1.equals(str3));//true

System.out.println(str4 == str6);//false
System.out.println(str4.equals(str6));//true
System.out.println(str7 == str4);//true
System.out.println(str4 == str8);//true
}
}
