class Position{
float x;
float y;
public Position(float x,float y){
this.x = x;
this.y = y;
}
public static void distence(source.x,source.y,target.x,target.y){
float distence1;
distence1 = (float)math.sqrt((double)(source.x-target.x)(source.x-target.x)-(source.y-target.y)(source.y-target.y));
System.out.println(distence1);
}
}
class TestPosition{
public static void main(String args []){
Position source = new Position(0.0f,0.0f);
Position target = new Position(1.0f,1.0f);
Position.distence(source.x,source.y,targer.x,target.y);
}
总是显示public static void distence(source.x,source.y,target.x,target.y){}错误 需要标志符

你想问什么。
...什么错误嘛.你一次说完啊兄弟
需要标志符??
什么意思哦
.
..你把错误贴出来
乘号没找到啊哥哥。
Java不会数学，不知道(1+1)(1+1)等于4。
