Check if a String is not empty ("") and not null in Java
Let’s say we have the following string −
String myStr1 = "Jack Sparrow";
Let us check the string now whether it is not null or not empty.
if(myStr != null || myStr.length() != 0) { System.out.println("String is not null or not empty");
Example
public class Demo { public static void main(String[] args) { String myStr = "Jack Sparrow"; boolean res; if(myStr != null || myStr.length() != 0) { System.out.println("String is not null or not empty"); } else { System.out.println("String is null or empty"); } } }
Output
String is not null or not empty
