Question

Can you tell me why this wont compile?

I am trying to run java an C together using JNI.

==============================

convert.java

import java.util.Scanner;
public class convert
{

public native float convertFtoC (int farenheight);
public native int roundTemp (int farenheight);

public static void main(String[] args)
{
System.loadLibrary("Convert");
convert convert = new convert();
System.out.println("Welcome");
Scanner input = new Scanner(System.in);
int farenheight;
float celcius;

System.out.println("Please Enter a Farenheight");

while (!input.hasNextInt())
{
input.next();
System.out.println("Invalid Input. Please Try again");
}

farenheight = input.nextInt();

System.out.println("Farenheight entered is: " + farenheight);

farenheight = convert.roundTemp(farenheight);
System.out.println("Rounded Temp is : " + farenheight);

celcius = convert.convertFtoC(farenheight);
System.out.println("Celcius is: " + celcius);
}

}

=====================

convert.c:

#include "convert.h"
#include <stdio.h>

JNIEXPORT jfloat JNICALL Java_convert_convertFtoC
(JNIEnv *env,jobject obj, jint farenheight)
{
float celcius;
celcius = (farenheight - 32) *(5.00/9.00);

return celcius;
}

JNIEXPORT jint JNICALL Java_convert_roundTemp
(JNIEnv *env,jobject obj, jint int)
{

if (temp %5 == 4.00)
{
temp = temp + 1.00;
}
else if(temp %5 == 3.00)
{
temp = *temp + 2.00;
}
else if(temp %5 == 2.00)
{
temp = temp + 3.00;
}
return temp;
}

===========================

convert.h

/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class convert */

#ifndef _Included_convert
#define _Included_convert
#ifdef __cplusplus
extern "C" {
#endif
/*
* Class: convert
* Method: convertFtoC
* Signature: (I)F
*/
JNIEXPORT jfloat JNICALL Java_convert_convertFtoC
(JNIEnv *, jobject, jint);

/*
* Class: convert
* Method: roundTemp
* Signature: (I)I
*/
JNIEXPORT jint JNICALL Java_convert_roundTemp
(JNIEnv *, jobject, jint);

#ifdef __cplusplus
}
#endif
#endif
