在Java中,如何使用使用continue語句?

下面範例中,演示如何使用continue語句跳過迴圈(實現統計指定字母(h)出現的次數,找到後路過迴圈)

package com.yiibai;

public class UseOfContinueStatement {
    public static void main(String[] args) {
        StringBuffer searchstr = new StringBuffer("hello how are you. ");
        int length = searchstr.length();
        int count = 0;

        for (int i = 0; i < length; i++) {
            if (searchstr.charAt(i) != 'h')
                continue;
            count++;
            searchstr.setCharAt(i, 'h');
        }
        System.out.println("Found " + count + " h's in the string.");
        System.out.println(searchstr);
    }
}

執行上面範例程式碼,得到以下結果 -

Found 2 h's in the string.
hello how are you.

範例2

以下是continue方法的另一個例子 -

package com.yiibai;

public class UseOfContinueStatement2 {
    public static void main(String[] args) {
        for (int i = 1; i <= 10; i++) {
            if (i == 5) {
                continue;
            }
            System.out.println(i);
        }
    }
}

執行上面範例程式碼,得到以下結果 -
