In Java, the method used for string extraction is substring(). This method has two different forms of overloading.<\/p>\n

    \n
  1. Extract a substring starting from the specified index position and return the substring from beginIndex to the end of the string.<\/li>\n
  2. Return the substring of the string starting at the specified index and ending at endIndex-1.<\/li>\n<\/ol>\n

    The example code is as follows:<\/p>\n

    String<\/span> str<\/span> =<\/span> \"Hello World\"<\/span>;\r\nString<\/span> sub1<\/span> =<\/span> str.substring(6<\/span>); \/\/ \u4ece\u7d22\u5f156\u5f00\u59cb\u622a\u53d6\u5b57\u7b26\u4e32\uff0c\u8fd4\u56de\"World\"<\/span>\r\nString<\/span> sub2<\/span> =<\/span> str.substring(0<\/span>, 5<\/span>); \/\/ \u4ece\u7d22\u5f150\u5230\u7d22\u5f154\u622a\u53d6\u5b57\u7b26\u4e32\uff0c\u8fd4\u56de\"Hello\"<\/span>\r\n<\/code><\/pre>\n
