Examples of java.lang.String.startsWith()

java.lang.String.startsWith()
Tests if the substring of this string beginning at the specified index starts with the specified prefix. @param prefix the prefix. @param toffset where to begin looking in this string. @return true if the character sequence represented by theargument is a prefix of the substring of this object starting at index toffset; false otherwise. The result is false if toffset is negative or greater than the length of this String object; otherwise the result is the same as the result of the expression
```
 this.substring(toffset).startsWith(prefix) 
```
