words count program

统计文本文件的字符数,单词数和行数。

实现一个统计程序,他能正确的统计程序文件中的字符数,单词数和行数。

心得:

在编写代码时首先考虑到要调佣哪个函数,在循环时是否会增加程序运行时间,在空字符,字符的处理问题上是否计算进去

测试用例

import java.util.Scanner;

public abstract class work{

public static void main(String[] args) {

Scanner reader = new Scanner(System.in);

boolean i = true;

int []num = new int[2];

System.out.print( "请输入每回合题目数量:" );

int z = (int)reader.nextInt();

while(i){

int sco = 0;

for(int w=0;w<z;w++){

for(int i1=0;i1<2;i1++)

num[i1] =  getnum();

if(getnum()%2==1){

System.out.print( num[0] + "+" + num[1] + "=" );

int h = (int)reader.nextInt();

int j = (int)(num[0]+num[1]);

Printf( j, h );

if (h==j)

sco++;

}

else{

int a=0, b=1;

if(num[0]-num[1]<0){a=1;b=0;}

System.out.print( num[a] + "-" + num[b] + "=" );

int h = (int)reader.nextInt();

int j = (int)(num[a]-num[b]);

Printf( j, h );

if (h==j)

sco++;

}

}

System.out.println("成绩是:" + (int)(((float)sco)/((float)z)*100.0 ));

System.out.println("是否继续:1/0");

int y = reader.nextInt();

if (y==0)

i = false;

}

}

private static int getnum() {

return (int)(Math.random()*10);

}

public static void Printf(int x,int y){

if(x==y)

System.out.println("恭喜你,回答正确!");

else

System.out.println("回答错误,正确答案是:" + "  " + x);

}

}
