A method which prints out if a strings starts with a character or not

Question

Below you can see what I have made :
public class StringZerleger {
public static void main(String args[]) throws Exception{
new StringZerleger().zerlegeString();
public void zerlegeString()
String s3 = "_a b c d";
String [] temp = null;
temp = s3.split(" ");
dump(temp);
public void istGueltigerBezeichner()
String s3 = String s3;
boolean b = s3.regionMatches( 1, "_", 1, 1 );
public void dump(String []s)
System.out.println("------------");
for (int i = 0 ; i < s.length ; i++)
System.out.println(s);
System.out.println("------------");
unfortunately it doesn't work as I want it to work.
Could someone help me please ?

It shouldn't even compile.
This method
public void istGueltigerBezeichner()
String s3 = String s3;
boolean b = s3.regionMatches( 1, "_", 1, 1 );
}1) is never called,
2) should return a boolean
3) should accept the string you are testing as a parameter
4) should be redone using a different method of String
private boolean istGueltigerBezeichner(String str)
if(str == null)
    return false;
return "_".equals(str.substring(0,1));
}Then call this method from with you loop, before your println statement
