如何用java提取字符串中的特定字母

Question

I have some expression in a Java string and a would get the letter, which was on the left side and on the right side of a specific sign.

Here are two examples:

X-Y
X-V-Y

Now, I need to extract in the first example the letter X and Y in a separate string. And in the second example, I need to extract the letters X, V and Y in a separate string.

How can i implemented this requirement in Java?

Answer 1

Try with:

String input    = "X-V-Y";
String[] output = input.split("-");  // array with: "X", "V", "Y"

Answer 2

use String.split method with "-" token

String input = "X-Y-V"
String[] output = input.split("-");

now in the output array there will be 3 elements X,Y,V

Answer 3

String[] results = string.split("-");

Answer 4

do like this

String input ="X-V-Y";
String[] arr=input.split("-");

output

arr[0]-->X
arr[1]-->V
arr[2]-->Y

Answer 5

我也加入了这个！

String[] terms = str.split("\\W"); // split on non-word chars

Answer 6

you can extract and handle a string by using the following code:

String input = "x-v-y";
String[] extractedInput = intput.split("-");
for (int i = 0; i < extractedInput.length - 1; i++) {
    System.out.print(exctractedInput[i]);
}

Output: xvy

Answer 7

You can use this method :

public String[] splitWordWithHyphen(String input) {
    return input.split("-");
}
