double型数组怎么转换成整型,用java

public class GetIt {
public static void main(String args[]){
double x[]={10.2,9.1,8.7};
int i[]=new int[3];
for(int a=0;a<(x.length);a++){

System.out.println(i[a]);
}
}

}

Answer 1

public class GetIt {
public static void main(String args[]){
double x[]={10.2,9.1,8.7};
int i[]=new int[3];
for(int a=0;a<(x.length);a++){
i[a] = (int)x[a];//增加这一句
System.out.println(i[a]);
}
}

}

Answer 2

二楼正解

Answer 3

我忘了是

i[a]=(int)x[a];

还是

i[a]=Integer.parse(x[a]);

了,你自己试试..
