# Java Generate Random Number Between Two Given Values

###### Posted By: Anonymous

I would like to know how to generate a random number between two given values.

I am able to generate a random number with the following:

```
Random r = new Random();
for(int i = 0; i < a.length; i++){
for(int j = 0; j < a[i].length; j++){
a[i][j] = r.nextInt();
}
}
```

However, how can I generate a random number between 0 and 100 (inclusive)?

## Solution

You could use e.g. `r.nextInt(101)`

For a more generic “in between two numbers” use:

```
Random r = new Random();
int low = 10;
int high = 100;
int result = r.nextInt(high-low) + low;
```

This gives you a random number in between 10 (inclusive) and 100 (exclusive)
