Java bytecode Directives

dealing with narrowing type conversions (Narrowing numberic Conversions), you must explicitly use conversion directives to accomplish these transformations, which include: i2b,i2c,i2s,l2i,f2i,f2l,d2i,d2l and d2f. Narrowing type conversions can result in a different sign and order of magnitude for the conversion result, and the conversion process is likely to result in a loss of precision in numeric values.Although the narrowing conversion of data typ
