Java如何从StringBuilder中删除子字符串？
本示例演示如何使用StringBuilderdelete(intstart,intend)和deleteCharAt(intindex)从中删除子字符串或单个字符StringBuilder。
package org.nhooo.example.lang;
public class StringBuilderDelete {
public static void main(String[] args) {
StringBuilder lipsum = new StringBuilder("Lorem ipsum dolor sit " +
"amet, consectetur adipisicing elit.");
System.out.println("lipsum = " + lipsum.toString());
//我们将从此StringBuilder中删除一个子字符串，从
//第一个字符到第28个字符。
lipsum.delete(0, 28);
System.out.println("lipsum = " + lipsum.toString());
//从StringBuilder中删除一个字符。在下面的示例中，我们
//删除最后一个字符。
lipsum.deleteCharAt(lipsum.length() - 1);
System.out.println("lipsum = " + lipsum.toString());
}
}上面的代码片段的结果：
lipsum = Lorem ipsum dolor sit amet, consectetur adipisicing elit. lipsum = consectetur adipisicing elit. lipsum = consectetur adipisicing elit
