The time it takes to create a thread increases as you create more thread. For the 32-bit JVM, the stack size appears to limit the number of threads you can create. This may be due to the limited address space. In any case, the memory used by each thread's stack add up. If you ...

2)、在JDK6.0及之前版本,字符串常量池是放在Perm Gen区(也就是方法区)中;可以运行如下代码,会报异常信息:java.lang.OutOfMemoryError:PermGen space 代码语言:javascript 复制 publicclassStringConstantPoolTest{publicstaticvoidmain(String[]args){List<String>list=Lists.newArrayList();while(true){list.add(Strin...
默认时,concurrencyLimit取值为-1,即不启用资源节流,所以它不是真的线程池,这个类不重用线程,每次调用都会创建一个新的线程(因此建议我们在使用@Aysnc的时候,自己配置一个线程池,节约资源) 然后看获取默认线程池的方法,这个方法很牛,先看代码后面解释为什么牛🐂【PS里面中文都是添加的,老外们不会中文】。
