isjava

Determine if input is Java object

Syntax

• tf = isjava(A)
  

Description

tf = isjava(A) returns logical 1 (true) if A is a Java object, and logical 0 (false) otherwise.

Examples

Create an instance of the Java Frame class and isjava indicates that it is a Java object.

• frame = java.awt.Frame('Frame A');
  
  isjava(frame)
  
  ans =
  
       1
  

Note that, isobject, which tests for MATLAB objects, returns logical 0 (false).

• isobject(frame)
  
  ans =
  
       0
