package org.arpit.java2blog; public class Convert0And1ToBoolean { public static void main(String[] args) { boolean boolean1 = getBoolean("1"); System.out.println("Boolean value for 1: "+boolean1); boolean boolean2 = getBoolean("0"); System.out.println("Boolean value for 0: "+boolean2); } public static boolean getBoolean(String value) { return !value.equals("0"); } } |
Output
