The lookingAt() method of Matcher Class attempts to match the pattern partially or fully in the matcher. It returns a boolean value showing if the pattern was matched even partially or fully starting from the start of the pattern. Syntax: 
  public boolean lookingAt()
Parameters: This method do not takes any parameter. Return Value: This method returns a boolean value showing if a prefix of the input sequence matches this matcher's pattern. Below examples illustrate the Matcher.lookingAt() method: Example 1: Java 
// Java code to illustrate lookingAt() method  import java.util.regex.*;  public class GFG {     public static void main(String[] args)     {          // Get the regex to be checked         String regex = "Geeks";          // Create a pattern from regex         Pattern pattern             = Pattern.compile(regex);          // Get the String to be matched         String stringToBeMatched             = "GeeksForGeeks";          // Create a matcher for the input String         Matcher matcher             = pattern                   .matcher(stringToBeMatched);          // Get the possible result         // using lookingAt() method         System.out.println(matcher.lookingAt());     } }
Output: 
  true
Example 2: Java 
// Java code to illustrate lookingAt() method  import java.util.regex.*;  public class GFG {     public static void main(String[] args)     {          // Get the regex to be checked         String regex = "GFG";          // Create a pattern from regex         Pattern pattern             = Pattern.compile(regex);          // Get the String to be matched         String stringToBeMatched             = "GFGFGFGFGFGFGFGFGFG";          // Create a matcher for the input String         Matcher matcher             = pattern                   .matcher(stringToBeMatched);          // Get the possible result         // using lookingAt() method         System.out.println(matcher.lookingAt());     } }
Output: 
  true
