（6-7）下面代码段属于普通构造块。
class Block{
{//代码1
System.out.println("1");
}
static{//代码2
System.out.println("2");
}
{//代码3
System.out.println("3");
}
public Block()
{//代码4
System.out.println("4");
}
}
class Block{
{//代码1
System.out.println("1");
}
static{//代码2
System.out.println("2");
}
{//代码3
System.out.println("3");
}
public Block()
{//代码4
System.out.println("4");
}
}
举一反三
- 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”) ; } }
- public class E4_1{ public static void main(String args[]) { int a = 1; int b = 2; int c = 3; a += 5; b *= 4; c += a * b; c %= 6; System.out.println("a = " + a); //代码1 System.out.println("b = " + b); //代码2 System.out.println("c = " + c); //代码3 }}运行结果,代码1______ ，代码2______ ，代码3______ 。
- 请看下面的程序代码,当 n 为( )值时,程序段将输出字符串 second。 [br][/br] switch(n) { [br][/br] case 0: System .out .println(“first”); [br][/br] case 1: [br][/br] case 2: System .out .println(“second”); break; [br][/br] default: System .out .println(“end”); [br][/br] }(2.0) A: 0 B: 1 C: 2 D: 以上都可以
- 【单选题】对于下面代码,正确的Java源程序文件名是( )。 class A { void method1() { System. out .println( "Method1 in class A" ); } } public class B { void method2() { System. out .println( "Method2 in class B" ); } public sta
