有一种方法,很多方法 其中一个可以是:

String string = "I want this split up into pairs";
String[] words = string.split(" ");
List<String> pairs = new ArrayList<String>();
for (int i = 0; i < words.length-1; ++i) {
    pairs.add(words[i] + " " + words[i+1]);
}
System.out.println(pairs);

这是一个基本的算法

对您的句子进行标记或分割

 I want this split up into pairs -> I, want, this, split, up, into, pairs

然后

first = read first word
while(there are more words to read){
    second = read next word
    Print first + " " + second
    first = second
}

一个例子如下:

    String text = "I want this split up into pairs";
    String[] words = text.split(" ");

    //Print 2 combined words
    for(int i=1;i<words.length;i++)
    {
        System.out.printf("%s %s\n", words[i-1],words[i]);
    }

控制台输出:

I want
want this
this split
split up
up into
into pairs

答案 3 :(得分:0)

不是一个庞大的java人,所以不确定这段代码是100%,但这是一个选项的一般想法。

    String x = "I want this split up into pairs";
    String[] parts = x.split(" ");
    List<String> newParts = new ArrayList<String>();;
    for (int i = 0; i < parts.length()-1; i++) {
        newParts.add(parts[i]+parts[i+1]);
    }

然后,newParts List将拥有你所有的对
