==== 7.5.29 iaload ====

Load int from array 

Format 

iaload 

Forms 

iaload = 39 (0x27) 

Stack 

..., arrayref, index -> ..., value.word1, value.word2 

Description 

The arrayref must be of type reference and must refer to an array whose components are of type int. The index must be of type short. Both arrayref and index are popped from the operand stack. The int value in the component of the array at index is retrieved and pushed onto the top of the operand stack. 

Runtime Exceptions 

If arrayref is null, iaload throws a NullPointerException. 

Otherwise, if index is not within the bounds of the array referenced by arrayref, the iaload instruction throws an ArrayIndexOutOfBoundsException. 

Notes 

In some circumstances, the iaload instruction may throw a SecurityException if the current context [[3.4_Contexts| Section 3.4, Contexts]]) is not the owning context ([[3.4_Contexts| Section 3.4, Contexts]]) of the array referenced by arrayref. The exact circumstances when the exception will be thrown are specified in Chapter 6 of the **//Runtime Environment Specification, Java Card Platform, Version 2.2.2//**. 

If a virtual machine does not support the int data type, the iaload instruction will not be available.
