Java编译时异常和运行时异常

package com.xiaohai;

import java.math.BigInteger;
import java.security.spec.ECPoint;
import java.text.SimpleDateFormat;
import java.util.*;


public class HelloWorld {

    public static void main(String[] args) {

        HelloWorld h=new HelloWorld();
        h.method();
    }
    //运行时异常
    public void method()
    {
        try {
            int[] arr = new int[]{1, 2, 4};
            for (int i = 0; i < 4; i++) {
                System.out.println(arr[i]);
            }
        }catch (Throwable e)
        {
            e.printStackTrace();
            System.out.println(e.getMessage());
            System.out.println(e.toString());
        }
    }
    //编译时异常
    public void method2()
    {
        String str=new String("2022-2-7");
        SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
        Date d=sdf.parse(str);
        System.out.println(d);
    }
}

解决：
方法一

//编译时异常
    public void method2()
    {
        try {
            String str=new String("2022-2-7");
            SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
            Date d=sdf.parse(str);
            System.out.println(d);
        }
        catch (Throwable e)
        {

        }
    }

方法二：

package com.xiaohai;

import java.math.BigInteger;
import java.security.spec.ECPoint;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.*;


public class HelloWorld {

    public static void main(String[] args) {

        HelloWorld h=new HelloWorld();
        try {
            h.method2();
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }
    //编译时异常
    public void method2() throws ParseException {
            String str=new String("2022-2-7");
            SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
            Date d=sdf.parse(str);
            System.out.println(d);
    }
}
