Java 分割字符串详解及实例代码

public class StringSplit {
  public static void main(String[] args) {
    String sourceStr = "1,2,3,4,5";
    String[] sourceStrArray = sourceStr.split(",");
    for (int i = 0; i < sourceStrArray.length; i++) {
      System.out.println(sourceStrArray[i]);
    }

    // 最多分割出3个字符串
    int maxSplit = 3;
    sourceStrArray = sourceStr.split(",", maxSplit);
    for (int i = 0; i < sourceStrArray.length; i++) {
      System.out.println(sourceStrArray[i]);
    }
  }
}
