怎樣把一下的C語言程序改成java程序？

修改成Java后的代碼：

c語言轉(zhuǎn)java，拜托各位

你要把這個(gè)轉(zhuǎn)為java程序么？

package?org.crazyit.app.ServletAPI;

import?java.util.Arrays;

import?java.util.Scanner;

public?class?Test?{

public?static?void?main(String[]?args)?{

char?[]?ax={'1','2'};

char[]?ac?=?reverse(ax);

System.out.println(Arrays.toString(ac));

char?sz[]?=?new?char[128];

System.out.println("請輸入你要轉(zhuǎn)換的數(shù)?:?");

Scanner?scanner?=?new?Scanner(System.in);

int?n?=?scanner.nextInt();

System.out.println("請輸入進(jìn)制?:?");

int?c?=?scanner.nextInt();

cover_to(n,?c,?sz);

System.out.println("轉(zhuǎn)換成?"?+?c?+?"進(jìn)制是?:"?+?Arrays.toString(sz));

}

public?static?void?cover_to(int?num,?int?base,?char?sz[])?{

int?t?=?num;

int?r?=?0;

int?n?=?0;

int?i?=?0;

if?(base??2?||?base??32)?{

return;

}

while?((n?=?t?/?base)?!=?t)?{

r?=?t?%?base;

t?=?n;

if?(r??9)

sz[i++]?=?(char)?('A'?+?(r?-?10));

else

sz[i++]?=?(char)?('0'?+?r);

}

sz[i]?=?0;

reverse(sz);

}

public?static?char?[]?reverse(char?[]?arr)?{

int?end=?arr.length-1;

int?begin?=0;

while(begin??end){

char?temp?=?arr[begin];??

arr[begin]?=?arr;??

arr?=?temp;??

begin++;??

end--;??

}

return?arr;

}

}

把C語言代碼轉(zhuǎn)成Java代碼

package dis;

import java.io.*;

import java.math.*;

public class dis

{

public static void main(String [] s) throws Exception

{

Float a,b,c;

double x2;

double x1;

System.out.println("請輸入a, b, c的值");

BufferedReader bReader=new BufferedReader(new InputStreamReader(System.in));

a=Float.parseFloat(bReader.readLine());

b=Float.parseFloat(bReader.readLine());

c=Float.parseFloat(bReader.readLine());

if (b*b - 4*a*c = 0)

System.out.println("輸入的系數(shù)不對，b2-4ac不大于0！程序退出！");

else

{

x1 = (-b + Math.sqrt(b*b - 4*a*c))/2*a;

x2 = (-b - Math.sqrt(b*b - 4*a*c))/2*a;

System.out.println("x1 = "+ x1);

System.out.println("x2 = "+x2);

}

return;

}

}
