Answer 1

答题完毕，代码全部测试通过。
本人英语一般，欢迎追问。

1)
int getSmaller(int a, int b) {return a<b? a:b;}

2)
boolean startSame(String a,String b){
String s1=a.substring(0, 1);
String s2=b.substring(0, 1);
if(s1.equalsIgnoreCase(s2))
return true;
else return false;
}

3)
//假设Die类如下
class Die{
int roll(){
return (int)(Math.random()*1000%5+1);
}
}

//则method为:
int rollTwo(Die a,Die b){
int count=0,sum=0;
for(int i=0;i<100;i++){
sum=a.roll()+b.roll();
if(sum==7||sum==11)
count++;
}
return count;
}

4)
class Employee{
String name,position;//本人假设position代表职位
long number;
int hourlyWage;
}

5)
double wage(int hours){
if(hours<=40)
return hours*hourlyWage;
else
return 40*hourlyWage+(hours-40)*hourlyWage*1.5;
}

补充：
1) d
2) b
3) c
4) e

望采纳。答得很辛苦，给点分吧。
