蓝桥杯基础练习VIP-矩形面积交 （Java代码）

解题思路:

注意事项:

参考代码:

import java.util.Arrays;

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner scanner=new Scanner(System.in);

double[] x=new double[4];

double[] y=new double[4];

double[] s=new double[4];

for (int i = 0; i < 4; i++) {

x[i]=scanner.nextDouble();

y[i]=scanner.nextDouble();

}

double max1=x[0]>x[1]?  x[0]:x[1];

double min1=x[2]<x[3]?  x[2]:x[3];

double max2=y[0]>x[1]?  y[0]:x[1];

double min2=y[2]<x[3]?  y[2]:x[3];

double S=0;

if(max1<min1){

S=0;

}else if (max2<min2) {

S=0;

}else {

Arrays.sort(x);

Arrays.sort(y);

if (x[0]==x[1]&&x[2]==x[3]) {

S=(x[2]-x[0])*(y[2]-y[1]);

}else if(y[0]==y[1]&&y[2]==y[3]){

S=(y[2]-y[0])*(x[2]-x[1]);

}else{

S=(x[2]-x[1])*(y[2]-y[1]);

}

}

System.out.printf("%.2f",S);

}

}
