标 题: 一道 JAVA Stack vs Heap 题
发信站: BBS 未名空间站 (Mon Nov 9 13:59:15 2009, 美东)
String s1 = "grapefruit";
String s2 = "grapefruit";
请问 s1 and s2 是在 stack 还是 heap 上呢？ Does s1 and s2 point to same
address?
String s3 = "grape"+"fruit";
Does s3 point to same address as s1 and s2?
String s4 = new String("grapefruit");
String s5 = new String("grapefruit");
s4 and s5 should be in heap, s4 and s5 should point to different addresses,
right?
System.out.print
