How can I split apart a string that has different amount of spaces into two parts?

I wanted to split one half to be a String mimeType and second half to be String ext

so far I implemented (str being the individual lines)

String mimeType="";
String ex = "";

String[] strArr = str.split("\t\t\t");

mimeType = strArr[0];
ex = strArr[1];

Since some don't have a second part, I keep getting errors. How do I go about fixing that?

Use \\s+ to split on spaces even if they're are multiple.

String mimeType="";
String ex = "";

String[] strArr = str.split("\\s+");

mimeType = strArr[0];
ex = strArr[1];

Just check the length of the array:

String[] strArr = str.split("\t\t\t");
mimeType = strArr[0];

if(strArr.length >= 2) {
    ex = strArr[1];
} else {
    ex = "None";
}
