i'm using a regular expression to check if we can use the scientific notation

here is what i have so far

private void SNotation(String [] data) {
int count =0;
boolean correct = false;
for (int i = 0; i < data.length; i++) {

if (str.matches(" /[+\-]?(?:0|[1-9]\d*)(?:\.\d*)?(?:[eE][+\-]?\d+)?/ "){
System.out.println(" it's a floating number ");
correct= true;
break;
}else
correct = false;

}if (correct ==true){
return true;
}else
return false;



}
