Java程序从字符串中删除前导和尾随引号
首先，让我们考虑一个带引号的字符串
String originalStr = "\"Demo Text\"";
现在，请看以下逻辑作为开始引用。
if (originalStr.startsWith("\"")) {
originalStr = originalStr.substring(1, originalStr.length());
}现在，请看以下逻辑作为结束语。
if (originalStr.endsWith("\"")) {
originalStr = originalStr.substring(0, originalStr.length() - 1);
}示例
public class Demo {
public static void main(String[] args) {
String originalStr = "\"Demo Text\"";
System.out.println("String with double quotes= "+originalStr);
if (originalStr.startsWith("\"")) {
originalStr = originalStr.substring(1, originalStr.length());
}
if (originalStr.endsWith("\"")) {
originalStr = originalStr.substring(0, originalStr.length() - 1);
}
System.out.println("String after removing double quotes = "+originalStr);
}
}输出结果
带双引号的字符串=“演示文本”删除双引号后的字符串=演示文本
