java开发_Runtime
public static void main(String[] a){
Runtime runtime = Runtime.getRuntime();
long freeMemoery = runtime.freeMemory();
long totalMemory = runtime.totalMemory();
long usedMemory = totalMemory - freeMemoery;
long maxMemory = runtime.maxMemory();
long useableMemory = maxMemory - totalMemory + freeMemoery;
System.out.println("当前时间:"+runtime);
System.out.println("系统闲置空间:"+freeMemoery);
System.out.println("系统总空间:"+totalMemory);
System.out.println("系统被用的空间:"+usedMemory);
System.out.println("系统最大空间:"+maxMemory);
System.out.println("系统可用空间:"+useableMemory);
}
运行效果:
当前时间:www.zzzyk.com
系统闲置空间:4873672
系统总空间:5177344
系统被用的空间:303672
系统最大空间:66650112
系统可用空间:66346440
