从一个较大的字符串字符中减去多个字符串可以通过以下几种方法实现:
replace()
函数,示例代码如下:large_string = "This is a large string containing multiple strings"
strings_to_remove = ["is", "a", "multiple"]
for string in strings_to_remove:
large_string = large_string.replace(string, "")
print(large_string)

replace()
函数结合正则表达式,示例代码如下:let largeString = "This is a large string containing multiple strings";
let stringsToRemove = ["is", "a", "multiple"];
for (let string of stringsToRemove) {
let regex = new RegExp(string, "g");
largeString = largeString.replace(regex, "");
}
console.log(largeString);

split()
函数和StringBuilder
类,示例代码如下:String largeString = "This is a large string containing multiple strings";
String[] stringsToRemove = {"is", "a", "multiple"};
StringBuilder result = new StringBuilder();
for (String part : largeString.split("\\s+")) {
boolean remove = false;
for (String string : stringsToRemove) {
if (part.equals(string)) {
remove = true;
break;
}
}
if (!remove) {
result.append(part).append(" ");
}
}
String finalString = result.toString().trim();
System.out.println(finalString);
