java运行时异常如果不捕获，异常抛出后，虚拟机会最终捕获异常，线程结束

java运行时异常可以捕获，从而让程序继续运行，

public class RunTimeExceptiontest {
	
	
	public RunTimeExceptiontest() {
		super();
	}
	
	public RunTimeExceptiontest(String name) throws Exception {
		super();
		this.str = name;
		throw new Exception("112233");
	}
	
	public String str = "";
	
	private int[] ints = new int[100];
	
	public void testints(){
		try {
			ints[101] = 1000;
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		System.out.print(100);
	}
	
	public static void main(String[] args) {
		
		RunTimeExceptiontest r = null;
		try {
			r = new RunTimeExceptiontest("1123");
				
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		r.testints();
		System.out.println(r.str);
			
		
		
		
	}
	
	public void tt(){
		
		SecurityManager sm =  System.getSecurityManager();
		
		System.setSecurityManager(sm);
	}
	
}
