testbreakandcontinue.java

有一个接口,用抽象类实现它的部分功能,再用实现类继承抽象类,实现其它没实现的接口方法

package cn.edu.csu.programmer;

public class TestBreakAndContinue {
  public static void main(String[] args) throws Exception {
    /*
     * out: for(int i = 0; i < 10; i++){ System.out.println("Out Loop"); in:
     * while(true){ int ch = System.in.read(); System.out.println("Inner Loop: " +
     * ch); if(ch == 'b'){ break in; } if(ch == 'q'){ break out; } } }
     */
    String srcStr = "Look for me";
    String subStr = "ook";
    boolean flag = false;
    int max = srcStr.length() - subStr.length();
    test: for (int i = 0; i <= max; i++) {
      int n = subStr.length();
      int j = i;
      int k = 0;
      while (n-- != 0) {
        if (srcStr.charAt(j++) != subStr.charAt(k++)) {
          continue test;
        }
      }
      flag = true;
      break test;
    }

    System.out.println(flag ? "找到子串" : "未找到子串");
  }
}
