Java writes a function to intercept a string, enter a string and byte number, and output a byte-truncated character. Requirements do not have a truncated condition __ data structure and algorithm

Title: Write a function that intercepts the string, input as a string and byte number, and output as a byte-truncated string. But to ensure that the Chinese character is not truncated half, such as "I abc" 4, should be truncated to "I ab", input "my ABC-def", 6, should be exported as "my ABC" instead of "I abc+ Han half." Requirements Analysis: 1. Input as
