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");
}
};
