在java 中怎么把double类型转成 int类型

Answer 1

兄弟给你最实用的两个方法：
double d = 3.14159;

//1
int i = (int)d;

//2

int i=Integer.valueOf(d);

Answer 2

double d = 1.23;
int i = (int) d;

Answer 3

double temp = 3.2546d;
int result = (new Double(temp)).intValue();
或者
double temp = 3.2546d;

int result = (int) temp;
