Nested If Statement in Java
It is perfectly all right if we write an entire if-else construct within either the body of the if statement or the body of an else statement.
Syntax :
if( boolean_expression 1) { /* Executes when the boolean expression 1 is true */ if(boolean_expression 2) { /* Executes when the boolean expression 2 is true */ } }
Example:
WAP to check the given natural number is even or odd.import java.util.Scanner; class Test { public static void main(String []arg) { Scanner sc; sc = new Scanner(System.in); int x ; System.out.print("Enter any number: "); x = sc.nextInt(); if(x>0) { if(x%2 == 0) System.out.print("X is EVEN"); else System.out.print("X is ODD"); } else { System.out.print("Not Natural Number"); } }//main closed }//class closedOUTPUT:
Enter any number: 12 X is EVEN
