java documentation code example

Example 1: isnumber java

// find value is number or not in java..
// if the value is number output is true 
// if the value is not a number then output is false.. 


public class Test {

   public static void main(String args[]) {
      System.out.println(Character.isDigit('c')); // false 
      System.out.println(Character.isDigit('5')); // true
   }
}

Example 2: java "->"

Runnable r = ()-> System.out.print("Run method");

// is equivalent to

Runnable r = new Runnable() {
            @Override
            public void run() {
                System.out.print("Run method");
            }
        };

Example 3: java docs

* simply displays "Hello World!" to the standard output.
*
* @author  Zara Ali
