10.5.1. intern 的使用:JDK6 vs JDK7/8 10.5.2. intern 的效率测试:空间角度 10.6. StringTable 的垃圾回收 10.7. G1 中的 String 去重操作 Motivation Spring Wonderland 17 March, 2025 我的标签 Java(25) JVM(24) HTML5(20) HTML(20)
与调用 intern 去重相比,G1 去重好处在于自动,但缺点是即使 char[] 不重复,但字符串对象本身还要占用一定内存(对象头、value引用、hash),intern 去重是字符串对象只存一份,更省内存 2.7 家的大小 安得广厦千万间,大庇天下寒士俱欢颜,风雨不动安如山
\nm —— 标识一个八进制转义值或一个向后引用。如果 \nm 之前至少有 nm 个获得子表达式,则 nm 为向后引用。如果 \nm 之前至少有 n 个获取,则 n 为一个后跟文字 m 的向后引用。如果前面的条件都不满足,若 n 和 m 均为八进制数字 (0-7),则 \nm 将匹配八进制转义值 nm。
