Test类的定义如下：publicclassTest{publicTest(){System.out.println(构造方法一被调用了。。);}publicTest(intx){System.out.println(构造方法二被调用了。。);}publicTest(booleanb){System.out.println(构造方法三被调用了。。);}publicstaticvoidmain(String[]args){Testtest=newTest(true);}}௲ 垎 뗐敔 敔垎�敘垎

- 中国大学MOOC: 下列代码中构造方法的返回类型是（）public class Village { Village () { System .out .println(“hiding in Village”) ; } public static void main( String args [ ]) { Village c =new Village ( ) ;}class Village { public static void main( String args [ ]) { Village c =new Village ( ) ; } Village () { System .out .println(“hiding in Village”) ; } }
- 设有如下程序，其调试结果为：classQ2{publicstaticvoidmain(String[]args){int[]seeds={1,2,3,4,6,8};intn=seeds.length;for(inti=0;i3;i++)for(intk=0;kn-1;k++)seeds[k]=seeds[k+1];for(inti=0;in;i++)System.ou௲ 垎 뗐敔 敔垎�敘垎၈Ǔ瘓礀Ǡ
