**G1 (Garbage-First) 是一款面向服务器的垃圾收集器,主要针对配备多颗处理器及大容量内存的机器. 以极高概率满足 GC 停顿时间要求的同时,还具备高吞吐量性能特征.**

被视为 JDK1.7 中 HotSpot 虚拟机的一个重要进化特征。它具备以下特点：

- **并行与并发**：G1 能充分利用 CPU、多核环境下的硬件优势，使用多个 CPU（CPU 或者 CPU 核心）来缩短 Stop-The-World 停顿时间。部分其他收集器原本需要停顿 Java 线程执行的 GC 动作，G1 收集器仍然可以通过并发的方式让 java 程序继续执行。
- **分代收集**：虽然 G1 可以不需要其他收集器配合就能独立管理整个 GC 堆，但是还是保留了分代的概念。
