把C语言代码转成Java代码

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("请输入察纯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("输入的系数不对，b2-4ac不大于0！程序退出！")

else

{

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

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

System.out.println("庆世x1 = "+ x1)

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

}

return

}

}

修改成Java后的代码：

public class Demo {

    public static int gcd(int a, int b, int c) {

        int min, i

        if(a > b) {

            }

        }

        for(i=min i>=1 i--) {

            if(a%i==0 && 绝态弯b%i==0 && c%i==0) {

     并闷           break

            }

        }

        System.out.println("N = " + k)

        System.out.println("N2 = " + j)

        System.out.println("N3 = " + m)

        System.out.println("N4 = " + n)

        i = gcd(a, b, c)

    }

}

public class Test{

public staitc void main(String args){

int i,j,k=3

for(i=0i<4k=k-1-i,i++)

{

for(j=0j<4+ij++)

{

if(j<k)

System.out.print(" ")

else

{

System.out.print("弯简*"信喊)

j++

}

}

}

k=3

}

}

保滑闹野存为Test.java，然后运行javac Test.java和java Test就可以运行了。。
