Question

把下面c++程序改成java，谢谢啊。

//求出str指向strlen串的长度。函数原型：int strlen(char *str)
#include<iostream>
using namespace std;
int strlen(char *str);
void main()
{
char a[80];
cout<<"输入字符串，输入c的值:\n";
cin>>a;
cout<<strlen(a)<<endl;
}
int strlen(char *str)
{
int pos = 0;
while ((*(str+pos))!='\0')
{
pos++;
}
return pos;
}
好多错误啊！！有没有可以执行的啊！谢谢啊

Answer 1

class Test{
public static void main(String[] args) {
System.out.println("输入字符串，输入c的值:\n");
BufferedReader bf=new BufferedReader(new InputStreamReader(System.in));
String str=bf.readLine();
int len=str.length();
System.out.println("长度"+len);
}
}

Answer 2

import java.io.IOException;
import java.io.*;
public class A
{
public sttaic int strlen(char *str)
{
int pos=0;
while((*(str+pos))!='\0')
{
pos++;
}
return pos;
}
public static void main(String args[])
{
String a;
int x;
System.out.println("输入字符串，输入c的值:");
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
a= br.readLine();
x=strlen(a);
System.out.println(x);

}
};
