push a constant #index from a constant pool (String, int, float, Class, java.lang.invoke.MethodType, java.lang.invoke.MethodHandle, or a dynamically-computed constant) onto the stack (wide index is constructed as indexbyte1 << 8 | indexbyte2) ldc2_w 14 0001 0100 2: indexbyte1, indexbyte2 → value
Byte values can be expressed in hexadecimal with the prefix \x followed by two hex digits: '\x1B' represents the Esc control character; "\x1B[0m\x1B[25;1H" is a string containing 11 characters with two embedded Esc characters. [3] To output an integer as hexadecimal with the printf function family, the format conversion code %X or %x is used.
The best-known is the string "From " (including trailing space) at the beginning of a line, used to separate mail messages in the mbox file format. By using a binary-to-text encoding on messages that are already plain text, then decoding on the other end, one can make such systems appear to be completely transparent .
Convert to an int16 (on the stack as int32) and throw an exception on overflow. Base instruction 0x83 conv.ovf.i2.un: Convert unsigned to an int16 (on the stack as int32) and throw an exception on overflow. Base instruction 0xB7 conv.ovf.i4: Convert to an int32 (on the stack as int32) and throw an exception on overflow. Base instruction 0x84
On most modern computers, this is an eight bit string. Because the definition of a byte is related to the number of bits composing a character, some older computers have used a different bit length for their byte. [2] In many computer architectures, the byte is the smallest addressable unit, the atom of addressability, say. For example, even ...
For example, a database persistence framework for Java objects might use Base64 encoding to encode a relatively large unique id (generally 128-bit UUIDs) into a string for use as an HTTP parameter in HTTP forms or HTTP GET URLs. Also, many applications need to encode binary data in a way that is convenient for inclusion in URLs, including in ...
Compiled to a 1-byte value, indicating an offset into the local variable frame. method name: The string name of a method. When compiled, the address of the method is calculated and put into the constant pool. This operand is then replaced with the 2-byte index (in the constant pool) of the address. constant name: The string name of a constant ...
