// Use split() to extract substrings from a string.class SplitDemo {  static void showSplit(String[] strs) {    for(String str : strs)      System.out.print(str + "|");    System.out.println("/n");  }  // Demonstrate split().  public static void main(String args[]) {    String result[];    // Split at spaces.    String testStr = "This is   a test.";    System.out.println("Original string: " + testStr);    result = testStr.split("//s+");    System.out.print("Split at spaces: ");    showSplit(result);    // Split on word boundaries.    testStr = "One, Two, and Three.";    System.out.println("Original string: " + testStr);    result = testStr.split("//W+");    System.out.print("Split at word boundaries: ");    showSplit(result);    // Split same string on commas and zero or more spaces.    System.out.println("Original string: " + testStr);    result = testStr.split(",//s*");    System.out.print("Split at commas: ");    showSplit(result);    // Split on word boundaries, but allow embedded    // periods and @.    testStr = "Jerry Jerry@HerbSchildt.com";    System.out.println("Original string: " + testStr);    result = testStr.split("[//W && [^.@]]+");    System.out.print("Allow . and @ to be part of a word: ");    showSplit(result);    // Split on various punctuation and zero or more trailing spaces.    testStr = "This, is. a!:; test?";    System.out.println("Original string: " + testStr);    result = testStr.split("[.,!?:;]+//s*");    System.out.print("Split on various punctuation: ");    showSplit(result);  }} 輸出：Original string: This is   a test.Split at spaces: This|is|a|test.|Original string: One, Two, and Three.Split at word boundaries: One|Two|and|Three|Original string: One, Two, and Three.Split at commas: One|Two|and Three.|Original string: Jerry Jerry@HerbSchildt.comAllow . and @ to be part of a word: Jerry|Jerry@HerbSchildt.com|Original string: This, is. a!:; test?Split on various punctuation: This|is|a|test|
