类Test1定义如下:1.public class Test1{2. public float aMethod(float a,float b){ }3.4.}将以下哪种方法插入行3是不合法的。
设有如下代码public class Test6{int attr[] = {1,2,3};public static void main ( String args[] ) {System.out.println(attr[0]);}}哪个叙述为真?
1.public class Test1{ 2. public float aMethod(float a,float b){ } 3. 4,} 将以下哪种方法差如行 3 是不合法的( )
题目:1. public class test (2. public static void main (String args[]) {3. int i = 0xFFFFFFF1;4. int j = ~i;5.6. }7. )程序运行到第5行时,j的值为多少?( )
类Test1定义如下: 1. public class Test1{ 2. public float aMethod(float a, float b){ } 3. 4. } 将以下哪种方法插入行3是不合法的。( )
智慧职教: 程序的执行结果是() public class Test { public static void main(String [] args){ System.out.println(“”+'a'+1); } }
分析如下所示的Java代码,则选项中的说法正确的是( )。 class Parent{ public String name; public Parent(String pName){ this.name = pName; } } public class Test extends Parent { //1 public Test(String Name){ //2 name=\hello
有如下程序:include<iostream>using namespace std;class Test{public:Test(){n+=2;}~Test(){n-
关于下面的程序Test.java说法正确的是()。public class Test {String x="1";int y;
下列程序的运行结果是()。 public class Test {public static void main (String[] args) {int count = 0 ;for(int i = 1 ; i < 5 ;i + = 2)for(int j = 1 ; j<= 10 ; j += 3)count ++ ;System
您可以在第几行的“?”位置上添加static关键字? 1 public class Test { 2 private int age; 3 4 public ? int square(int n) { 5 return n * n; 6 } 7 8 public ? int getAge() { 9 } 10}
下列代码中,将引起一个编译错误的行是 1) public class Test 2) int m,n; 3) public Test() 4) public Test(int
执行下列程序段后输出的结果是______。 public class Test public static void main(String args)int x,y;for(y=1,x=1;y<=50;y++) if(x>=10)break; if (x%2==1) x+=5; continue; x-=2;System.out.println(y);
