Can someone help with this java coding?

Answer 1

Okay, so I'm trying to make a mod in minecraft. I'm inside the ei.class (I changed it to ei.java) file in minecraft. I'm not trying to change anything, I just opened the file and compiled it. When I try to compile the code, it says:

--- Errors:
Line Number: 24 Line:
/Applications/Minecraft/ei.java:24: unreported exception java.io.IOException; must be caught or declared to be thrown /* 22 */ this.a = paramDataInput.readInt( );

And it says the same thing but for line 29. Here is the code:

/* */ public void a(DataInput paramDataInput)
/* */ {
/* 24 */ this.a = paramDataInput.readInt();
/* */ }

/* */ public void a(DataOutput paramDataOutput)
/* */ {
/* 29 */ paramDataOutput.writeInt(this.a);
/* */ }

I basically know nothing about java coding, but I'm trying! Thanks in advance.
