这个是可以导致Exception in thread "main" java.lang.OutOfMemoryError: Java heap space 的代码: public class TestGC { private String largeString = new String(new byte[100000]); String getString() { return this.largeString.substring(0, 2);//在JDK6里会导致out of memory,在JDK7和8不会出现问...

你了解Java中String的substring函数吗? Java中的substring函数是我们经常使用的一个函数,用来截取当前字符串的子串,定义如下: publicfinalclassString{publicString substring(intbeginIndex);publicString substring(intbeginIndex,intendIndex); } 使用及声明都非常简单,但是你了解其中的细节吗?
