7.5.86 sastore

Store into short array




sastore = 57 (0x39)


…, arrayref, index, value → …


The arrayref must be of type reference and must refer to an array whose components are of type short. The index and value must both be of type short. The arrayref, index and value are popped from the operand stack. The short value is stored as the component of the array indexed by index.

Runtime Exception

If arrayref is null, sastore throws a NullPointerException.

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


In some circumstances, the sastore instruction may throw a SecurityException if the current context ( Section 3.4, Contexts) is not the owning context ( 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.
