好多编程题啊，有时间再说咯
一、判断题 1.×2.√ 3.× 4.× 5.×6.×7.×8.×9. √ 10.√二、选择题 1.A 2.B 3.B 4.B 5.C 6.C 7.D 8.C 9.D 10.D
三、程序分析
public class example{
public static void main(String args[]){
int x=1
if (x>0) x=2
switch(x){
case 1: System.out.println(1)
case 0: System.out.println(0) break
case 2: System.out.println(2)
case 3: System.out.println(3) break
default:System.out.println(4) break }
输出2,3
2．以下语句输出的结果是 。
String str=”123”
int x=4,y=5
str=str+(x+y)
System.out.println(str)
输出1239
你好！

}
}
希望对你有帮助！
