Given the following variable declarations, independently consider the given 6 sequences of Java instructions.

 String string = "bat"; Integer x = 7; Object[] objects; List rawList; List < Object > objectList; List < String > stringList; 

Identify any code that results in a compiler error or warning. Identify any code that raises a runtime exception. Once a compiler error is noted, you do not need to analyze the sequence further.

objects = new String[1]; objects[0] = string;
