J2EE 部分1、运算符优先级问题，下面代码的结果是多少？(笔试)packagetest;publicclassTest{publicstaticvoidmain(String[]args){intk=0;intret=++k+k+++++k+k;//ret 的值为多少}}2、运算符问题，下面代码分别输出什么？(笔试)packagetest;publicclassTest{publicstaticvoidmain(String[]args){inti1=10,i2=10;}}3、下面代码的结果是什么？还是抛出异常？(笔试)packagetest;publicclassTest{publicvoidmyMethod(Stringstr){}publicvoidmyMethod(Objectobj){}publicstaticvoidmain(String[]args){Testt=newTest();t.myMethod(null);}}4、假设今天是 9 月 8 日，下面代码输出什么？(笔试)packagetest;publicclassTest{publicstaticvoidmain(String[]args){Datedate=newDate();}}5、下面代码的输出结果是什么？packagetest;publicclassTest{publicstaticvoidmain(String[]args){doubleval=11.5;}}6、下面代码的结果是什么？packagetest;publicclassTestextendsBase{publicstaticvoidmain(String[]args){Baseb=newTest();b.method();Testt=newTest();t.method();}@Overridepublicvoidmethod(){}}classBase{publicvoidmethod()throwsInterruptedException{}}7、以下代码的结果是什么？packagetest;publicclassTestextendsBase{publicstaticvoidmain(String[]args){newTest().method();}publicvoidmethod(){getName());}}classBase{}8、trueorfalse?packagetest;publicclassTest{publicstaticvoidmain(String[]args){Stringstr1=newString("abc");Stringstr2=newString("abc");StringBuffersb1=newStringBuffer("abc");StringBuffersb2=newStringBuffer("abc");9、输出的结果是什么？packagetest;publicclassTest{publicstaticvoidmain(String[]args){Syste}publicintmethod1(){intx=1;try{returnx;}finally{++x;}}publicintmethod2(){intx=1;try{returnx;}finally{return++x;}}}这样呢？输出什么packagetest;publicclassTest{publicstaticvoidmain(String[]args){}publicstaticbooleanmethod(){try{returntrue;}finally{returnfalse;}}}10、方法 ml 和 m2 有区别吗？什么区别packagetest;publicclassTest{publicstaticvoidmain(String[]args){}publicsynchronizedvoidm1(){}publicstaticsynchronizedvoidm2(){}}11、trueorfalse?理由 packagetest;publicclassTest{publicstaticvoidmain(String[]args){Integeri1=127;Integeri2=127;11 =128;...
