[java]用java编写一个程序:计算圆,三角形,长方形的面积,做比较后选出最大的显示出来

我先给你写下...等下给你...

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Area {

public void getInputString() {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

double banjing = 0;//半径
double di = 0;//底
double gao = 0;//高
double chang = 0;//长
double kuan = 0;//宽

System.out.println("输入圆形的半径: ");
try {
banjing = Integer.valueOf(br.readLine());
} catch (Exception e) {
e.printStackTrace();
}

System.out.println("输入三角形的底: ");
try {
di = Integer.valueOf(br.readLine());
} catch (Exception e) {
e.printStackTrace();
}

System.out.println("输入三角形的高 ");
try {
gao = Integer.valueOf(br.readLine());
} catch (Exception e) {
e.printStackTrace();
}

System.out.println(&q
