Scanner nextLine() method in Java with Examples Last Updated : 12 Oct, 2018 Summarize Comments Improve Suggest changes Share Like Article Like Report Try it on GfG Practice The nextLine() method of java.util.Scanner class advances this scanner past the current line and returns the input that was skipped. This function prints the rest of the current line, leaving out the line separator at the end. The next is set to after the line separator. Since this method continues to search through the input looking for a line separator, it may search all of the input searching for the line to skip if no line separators are present. Syntax: public String nextLine() Parameters: The function does not accepts any parameter. Return Value: This method returns the line that was skipped Exceptions: The function throws two exceptions as described below: NoSuchElementException: throws if no line was found IllegalStateException: throws if this scanner is closed Below programs illustrate the above function: Program 1: Java // Java program to illustrate the // nextLine() method of Scanner class in Java // without parameter import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { String s = "Gfg \n Geeks \n GeeksForGeeks"; // create a new scanner // with the specified String Object Scanner scanner = new Scanner(s); // print the next line System.out.println(scanner.nextLine()); // print the next line again System.out.println(scanner.nextLine()); // print the next line again System.out.println(scanner.nextLine()); scanner.close(); } } Output: Gfg Geeks GeeksForGeeks Program 2: To demonstrate NoSuchElementException Java // Java program to illustrate the // nextLine() method of Scanner class in Java import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { String s = ""; // create a new scanner // with the specified String Object Scanner scanner = new Scanner(s); System.out.println(scanner.nextLine()); scanner.close(); } catch (Exception e) { System.out.println("Exception thrown: " + e); } } } Output: Exception thrown: java.util.NoSuchElementException: No line found Program 3: To demonstrate IllegalStateException Java // Java program to illustrate the // nextLine() method of Scanner class in Java // without parameter import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { String s = "Gfg"; // create a new scanner // with the specified String Object Scanner scanner = new Scanner(s); scanner.close(); // Prints the new line System.out.println(scanner.nextLine()); scanner.close(); } catch (Exception e) { System.out.println("Exception thrown: " + e); } } } Output: Exception thrown: java.lang.IllegalStateException: Scanner closed Reference: https://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html#nextLine() Comment More infoAdvertise with us Next Article Scanner nextLine() method in Java with Examples G gopaldave Follow Improve Article Tags : Java Java-Library Java - util package Java-Functions Practice Tags : Java Similar Reads Scanner nextInt() method in Java with Examples The nextInt(radix) method of java.util.Scanner class scans the next token of the input as a Int.
