PrefixCalc

[MethadoneBoy]

Does anyone know how to modify the prefixCalc method here so that it won't print out "Infinity..." when run?

class Prefix {

static float a[] = {2,8,2,8,5,11};

static void prefixCalc(float Arr[]) {

try {

Arr = a;

for (int i = 0; i < Arr.length; i ++) {

for (int j = 0; j <= i; j ++) {

Arr[i] += Arr[j];
Arr[i] /= i;

}

}

} catch (Exception e) {}

}

public static void main( String args[] ) {

prefixCalc(a);

System.out.print("prefix averages =");

for (int i = 0; i < a.length; i++)

System.out.print(" " + a[i]);

System.out.println();

}

}




Thanks

I ran your code and changed it alittle so i could see what was going on. It seems that you are dividing a floating point number by 0 which results in Positive Infinity.

class Prefix { 

static float a[] = {2,8,2,5}; 

static void prefixCalc(float Arr[]) { 

try { 

Arr = a; 

for (int i = 0; i < Arr.length; i ++) { 

for (int j = 0; j <= i; j ++) { 

Arr[i] += Arr[j];
System.out.println(Arr[i] + " + "  + Arr[j]);
Arr[i] /= i; 
System.out.println(Arr[i] + " / "  + i); 
} 

} 

} catch (Exception e) {} 

} 

public static void main( String args[] ) { 

prefixCalc(a); 
/*
System.out.print("prefix averages ="); 

for (int i = 0; i < a.length; i++) 

System.out.print(" " + a[i]); 

System.out.println(); 
*/
}
