怎样把一下的C语言程序改成java程序？
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) {
if(b c) {
min = c;
} else {
min = b;
}
} else {
if(a c) {
min = c;
} else {

public static void main(String[] args) {

}
}
这段C代码如何转为java代码？
public class Test {
private int HASH_LOG = 14;
private int HASH_SIZE=(1 HASH_LOG);
private int HASH_MASK=(HASH_SIZE - 1);
public Long flz_hash(Long a){
Long l1 = 2654435769L;
Long index = (a * l1) 32-HASH_LOG;
return index HASH_MASK;
}
public static void main(String[] args) {
Test test = new Test();
long a = 2;
Long index = test.flz_hash(a);
System.out.println(index);
}
}
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))/2*a;
x2 = (-b - Math.sqrt(b*b - 4*a*c))/2*a;
System.out.println("x1 = "+ x1);
System.out.println("x2 = "+x2);
}
return;
}
}
