EXCEPTION-HANDLING-IN-JAVA

(1)SIMPLE   TRY CATCH:
package first;

public class excep1 {
public static void main(String []s)
{
try
{
int a=10,b=0,c;
c=a/b;
System.out.println("the ans is "+c);
}catch(Exception e){System.out.println ("divident can not be zero");}
}

}

(2)NESTED TRY CATCH:

package first;

public class ntry {

public static void main(String []s)

{

int x[]={45,67};

try

{

int a=10,b=0,c;

c=a/b;

try

{

x[0]=45;

x[1]=22;

}catch(ArrayIndexOutOfBoundsException e){System.out.println(e);}

}catch(ArithmeticException e1){System.out.println("divisior can not be zero");}

finally

{

x[1]=23;

System.out.println(x[0]+" :"+x[1]);

}

}

}

(3)MULTIPLE  CATCH:

package first;

public class mcatch {

public static void main(String []s)

{

try

{

int a=10,b=1,c;

c=a/b;

int x[]={45,67};

x[20]=45;

}catch(ArrayIndexOutOfBoundsException e){System.out.println("index should be in range");

}catch(ArithmeticException e1){System.out.println("divisior can not be zero");}

}

}

(4)Custom  Exception:

package first;

public class custexcep {

public static void main(String []om)

{

int m=134;

try

{

 if(m>100)

 throw new myexception ("marks exceeed the limit");   //human h=new human();

 System.out.println("marksl are"+m);

}catch(myexception e)

{System.out.println(e.getMessage());}

}

}

class myexception extends Exception

{

myexception (String s)

{

super(s);

}

}
