似乎函数中声明的静态变量在调用函数时会重新初始化,我如何以重新调用函数将重新使用静态参数的方式使用函数?我在static.php中定义了函数'testStatic'这是static.php:我正在从index.php调用“testStatic”这里是index.php:...当第一次执行index.php时,testStatic将返回“0”,但在下一次执行index.php时,testStatic将继续返回“0”。似乎每当执行index.php时,都会重新启动“testStatic”的静态变量“staticV”。请指教。那个index.php 最佳答案
为什么下面的代码没问题,但是一将T作为泛型添加到Main中,就抛出如下错误?'Main.this'cannotbereferencedfromastaticcontext//publicclassMain{-uncommentthisfortheerrortoappearpublicclassMain{publicstaticvoidmain(String[]args){newMain();}classTestNonStatic{}privatestaticclassTestStatic{publicTestStatic(TestNonStaticnonStatic){//thisis
