subString

[Mark Henryson]

class Stringex
{
  public static void main(String args[])
  {
    String s1 = "Hello";
    String s2 = "Hello";
    String s3 = new String("Hello");
    String s4 = new String("Hello"); 
    String s5 = " World";
 
    System.out.println(s1 == s2);
    System.out.println(s3 == s4);     
    System.out.println(s1 == s3);         
    System.out.println(s2 == s4);     
 
    System.out.println("***********************");        
 
    System.out.println(s1.equals(s2));         
    System.out.println(s3.equals(s4));         
    System.out.println(s1.equals(s3));         
    System.out.println(s2.equals(s4));         
 
    System.out.println("***********************");            
    
    System.out.println("Concat    :"+" "+ s3.concat( s5));
    System.out.println("Replace   :"+" "+s5.replace('o','a'));
[B] System.out.println("SubString:"+" "+s5.subString(1,3));[/B]
  }
} 

In the above code why the subString() is not working. It shouw some error message:

java
Stringex.java:27: cannot resolve symbol
symbol  : method subString  (int,int)
location: class java.lang.String
    System.out.println("SubString:"+" "+s5.subString(1,3));
                                          ^
1 error

try it with s5.substring instead of s5.subString

In these cases it's always best to check the jdk api documentation for the method pointed to by the error message, s5.subString in this case.

Just look up the String class and check it's methods to see if the method name and the arguments are in order.

i think it is substring...not subString...
