There are two forms of String.startsWith() methods.
- startsWith(String prefix) - Tests if this string starts with the specified prefix.
- boolean startsWith(String prefix, int toffset) - Tests if the substring of this string beginning at the specified index starts with the specified prefix.
The startsWith() method determines whether a given String begins with a specified string.
This is a complete example to demonstrate the usage of startsWith() methods.
public class StartsWithExample {
public static void main(String[] args) {
String str = "javaguides";
boolean startWith = str.startsWith("ja");
System.out.println("startWith :: " +startWith);
// Remember index starts from 0
boolean startWithOffset = str.startsWith("guides", 4);
System.out.println("startWithOffset :: " + startWithOffset);
}
}
Output:
startWith:: true startWithOffset:: true
