Load float
from array
Bytecode
Type | Description |
u1 | faload opcode = 0x30 (48) |
Stack ..., arrayref, index =>..., value
Retrieves an entry from a float array and places it on the stack. arrayref is a reference to an array of single-precision floats. index is an int. The arrayref and index are removed from the stack, and the single-precision float entry at the given index in the array is pushed onto the stack.
The arrayref must be of type reference
and must refer to an array
whose components are of type float
.
The index must be of type int
. Both arrayref and index
are popped from the operand stack.
The float
value in the component of the array at index is
retrieved and pushed onto the top of the operand stack.
; This is like the Java code: ; float x = arr[0]; ; where x is local variable 2 and arr is a float ; array in local variable 1 aload_1 ; load local variable 1 onto the stack iconst_0 ; push the integer 0 onto the stack faload ; retrieve the entry fstore_2 ; store the entry in local variable 2
Exceptions
NullPointerException - arrayref is null
ArrayIndexOutOfBoundsException - index is < 0 or >= arrayref.length
