Get 2 doubles from a string

I am passing some data from another class. This string I pass is:

"23 n 5"

Now I have 2 instance Double variables called a and b.

My aim is to take this and place 23 in a and 5 in b. The n is a splitter. Any number can be either side.

i'm sure the code must be really simple here. But, i'm not sure what to put in. Any help would be greatly appreciated. 

  public Double x(String x){
        if (x.contains(" n ")){
 <code need help on> }

public void x(String x)
{
    if (x.contains(" n "))
    {
        String[] s = x.split(" n ");
        a = Double.parseDouble(s[0]);
        b = Double.parseDouble(s[1]);
    }
}

Try This:

String[]arr=x.trim().split("n");
double a=Double.parseDouble(arr[0]);
double b=Double.parseDouble(arr[1]);

Use String#split:

String[] split = input.split(" n ");  // the argument can be a regular expression
