已知一窗体上命令按钮Command1的Click事件代码如下,则单击Command1后,文本显示的文字为()。 PrivateSubCommand1_Click() Text1.Text="湖南省"&"计算机"+"等级考试" Text1.ForeColor=vbRed Text1.BackColor=vbGreen Text1.FontBold=True EndSub
public class X { public static void main (Stringargs) { String s1 = new String (“true”); Boolean b1 = new Boolean (true); if (s2.equals(b1)) { System.out.printIn(“Equal”); } } } What is the result? ()
已知如下代码:booleanm=true;if(m=false)System.out.println("False");elseSystem.out.println("True");执行结果是()
public void testIfA(){ if(testIfB("True")){ System.out.println("True"); }else{ System.out.println("Nottrue"); } } public Boolean testIfB(Stringstr){ return Boolean.valueOf(str); } What is the result when method testIfA is invoked?()
class Test4 { public static void main(String [] args) { boolean x = true; boolean y = false; short z = 42; if((z++ = = 42) && (y = true)) z++; if((x = false) (++z = = 45)) z++; System.out.println("z = " + z); } } 结果为:()
class Test2{ public static void main(String [] args){ boolean x=true; boolean y=false; short z=42; if((x==true)&&y=true))z++; if((y==true++z=44))z++; System.out.println(“z=”+z); } } 结果是什么?()
测试如下代码:public class Ref{public static void main(String[] args) {StringBuffer sbl = new StringBuffer(Hello);StringBuffer sb2 = new StringBuffer(Hello);boolean result = sbl.equals(sb2);System.out.println(result);}}下述哪条语句正确描述了程序编译和运行的行为?
在java语言中,boolean型常量只有true和_____两个值。
以下代码的调试结果为?1: public class Q102: {3: public static void main(String[] args)4: {5: int i = 10;6: int j = 10;7: boolean b = false;8:9: if( b = i == j)10: System.out.println(\True\);11: else12: System.out.println(\False\);13: }14: }
设有如下代码: class Base{} public class MyCast extends Base{ static boolean b1=false; static int i = -1; static double d = 10.1; public static void main(String argv[]){ MyCast m = new MyCast(); Base b = new Base(); //Here } } 则在 //Here处插入哪个代码将不出现编译和运行错误。
以下 Visual Basic 代码的运行结果为 ________。 D im a as Integer , b as Boolean ,c as String b=True a=b c=a b= c + 1 print a,b,c
测试如下代码: public class Ref{ public static void main(String[] args) { StringBuffer sbl = new StringBuffer(\Hello\); StringBuffer sb2 = new StringBuffer(\Hello\); boolean result = sbl.equals(sb2); System.out.println(result); } } 下述哪条语句正确描述了程序编译和运行的行为?
已知如下代码段:boolean x=false;boolean y=true;boolean z=(x&&y)&&(!y) ;int f=z==false?1:2;执行完这段代码后,z的值是( ),f的值是( )
已知代码如下:void main(){float num【4】={12.5,78.9,2.3},m;m=num【0】;if(m<num【1】){m=num【1】;}printf("%f",m);}程序输出的结果不正确的是()
写出下列表达式的值, (1)已知int x=2; boolean bool = true。 表达式:bool|| (x==3)&(x==2) (2)已知int x=2; 表达式:x*=3+5 (3)已知int x=2; 表达式:24>>2*x
3、设各个变量的定义如下,哪些选项的值为 true() int a=3,b=3; boolean flag=true;
将布尔(boolean)值用于算术运算或转换为数值时,TRUE转换为1,FALSE转换为0。将boolean值转换为字符串时,TRUE转换为字符串'1',FALSE转换为'0'。()此题为判断题(对,错)。
有如下代码:inta=1,b=2;booleanx=true,y=true,z=true;z=(y=(a>b))&&(x=(b==3));,执行完之后x的值为false。()此题为判断题(对,错)。
已知如下代码:switch(m){ case 0: System.out.println(“Condition 0”); case 1: System.out.println(“Condition 1”); case 2: System.out.println(“Condition 2”); case 3: System.out.println(“Condition 3”);break; defa
7、以下代码片段编译运行的结果是:int Output=10; boolean b1 = false; if((b1==true) && ((Output+=10)==20)){ System.out.println("We are equal "+Output); } else { System.out.println("Not equal! "+Output); }
给定某Java程序的main方法如下所示,该程序的运行结果是public static void main(String[] args) {boolean boo = true;if (boo == false) {System.out.println(“a”);} else {System.out.println(“b”);}}()
下列代码段给even变量赋Boolean值: Code 1: if () true: false; Code 3: even = number % 2 == 0;
某人编写了如下函数来判断a是否为素数,若是,则函数返回True;否则返回False。 Function Prime(a As Integer) AS Boolean Dim k As Interger, isprime AS Boolean If a<2 Then isprime=False EIse isprime=True k=2 Do While k If a Mod k=0 Then ip
