# How to fix my output of number of runs

I want to print out how many times Math.random() was less that 0.5 and how many thimes it was bigger that 0.5. So I use int sum variable and increase it each time as you can see in the code:

```package shapes;

public class Main {

public static void main(String[] args) {

for (int i=1; i<6; i++){
int sum1=0;
if(Math.random()<0.5){
System.out.println("head");
System.out.println(Math.random());
sum1++;
System.out.println("sum of head"+sum1);

}else {
int sum2=0;
System.out.println("tail");
System.out.println(Math.random());
sum2++;
System.out.println("sum of tail"+sum2);
}
}

}

}
```

My output is :

```tail
0.2420579681161944
sum of tail1
head
0.712979930711983
sum of head1
tail
0.28072067461911476
sum of tail1
head
0.5897197845744805
sum of head1
head
0.6735600614954825
sum of head1
```

I want the output to be like this :

```tail
0.2420579681161944
head
0.712979930711983
tail
0.28072067461911476
head
0.5897197845744805
head
0.6735600614954825
sum of head 3
sum of tail 2
```

I actually tried to put sum1++ and sum2++ in different places but did not worked . thanks

## Answer

You reset sum to 0 each time in the for loop. Move your sums variable declaration out of the loop.

```int sum1=0;
int sum2=0;
for (int i=1; i<6; i++){
double val = Math.random();
if(val<0.5){
sum1++;
}else {
sum2++;
}
System.out.println("sum of head "+sum1);
System.out.println("sum of tail "+sum2);
}
```
