Question

Write a sample Java code that run of the program should look something like output:

  • use the .length(), .substring(), .indexof(), functions in your code.
  • Note:

    The important thing to note here is that the "4" in input.substring(0,4) is the index of the space character, and the "5" in input.substring(5) is that index plus 1. So we can get the first and last names using:

    space = input.indexOf(' '); firstName = input.substring(0,space); // Everything before the space lastName = input.substring(space+1); // Everything after the space

    By the way, this program will only work correctly if the user follows the instructions. If the user's input does not contain a space, then the value of input.indexOf(' ') will be -1, and the -1 will cause the program to crash when used in the substring function

J space = input.java X
C: > Users > reshm > J space= input.java

public class sample {

public static void main (String[] args) {

}
input.indexOf(' ');
input.substring (0, space); // Everything before the space
input.substring (space+1); // Everything after the space
