本文整理了Java中java.lang.String.regionMatches()方法的一些代码示例，展示了String.regionMatches()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。String.regionMatches()方法的具体详情如下：
包路径：java.lang.String
类名称：String
方法名：regionMatches

String.regionMatches介绍

[英]Tests if two string regions are equal.

A substring of this String object is compared to a substring of the argument other. The result is true if these substrings represent identical character sequences. The substring of this String object to be compared begins at index toffset and has length len. The substring of other to be compared begins at index ooffset and has length len. The result is false if and only if at least one of the following is true:

  • toffset is negative.
  • ooffset is negative.
  • toffset+len is greater than the length of this String object.
  • ooffset+len is greater than the length of the other argument.
  • There is some nonnegative integer k less than len such that: this.charAt(toffset+k) != other.charAt(ooffset+k)
    [中]测试两个字符串区域是否相等。
    将此字符串对象的子字符串与另一个参数的子字符串进行比较。如果这些子字符串表示相同的字符序列，则结果为真。要比较的字符串对象的子字符串从索引toffset开始，长度为len。要比较的其他字符串的子字符串从索引ooffset开始，长度为len。当且仅当以下至少一项为真时，结果为假：
    *toffset为阴性。
    *ooffset是负数。
    *toffset+len大于此字符串对象的长度。
    *ooffset+len大于另一个参数的长度。
    *有一些非负整数k小于len，这样：这个。字符（toffset+k）=其他的。字符（ooffset+k）
