从Java中的StringBuilder中删除子字符串
为了从JavaStringBuilder对象中删除子字符串，我们使用delete()方法。该delete()方法从序列中删除范围内的字符。该delete()方法有两个参数，开始和结束。字符从头到尾的索引1删除。
声明-java.lang.StringBuilder.delete()方法声明如下-
public StringBuilder delete(int start,int end)
让我们看一个示例，该示例从StringBuilder中删除子字符串。
示例
public class Example {
public static void main(String[] args) {
StringBuilder sb = new StringBuilder("Welcome to Java Programming");
System.out.println("Original StringBuilder Object: " + sb.toString());
sb.delete(4,10);
System.out.println("New StringBuilder Object: " + sb.toString());
}
}输出结果
Original StringBuffer Object: Welcome to Java Programming New StringBuffer Object: Welc Java Programming
