technology operation characteristics: Multi-channel, macro-parallel, micro-serial. Concurrency: In the operating system, there are several programs in a period of time that are running from the start to completion, and the programs are running on the same processor, but only one program is running on the processor at any one time point. Throughput: throughput refers to the number of successful data transfers (measured in bits, bytes, packets, and so on) over a network, device, port, virtual cir

as follows:? 1 str.substring (M, N) + ""This creates an entirely new array of characters representing the new string. The method above sometimes makes the code faster because the garbage collector reclaims large unused strings, leaving only one substring.In Oracle JDK 7, SUBSTRING () creates a new character array without an existing array. The substring () Method in JDK 6 and JDK 7 shows the difference between JDK 6 and JDK 7 substring ().String vs StringBuilder vs StringBufferString vs Stringb
