Question

how is this java program wrong?
public class Homework3 {

public static void main(String[]args){
for (int i=1;i<=10;i++){
for (int k=1;k<=10;k++);{
System.out.println(i+"x"+j=+(i*j))
}
}
}

}

Output should be
1 x 1 = 1
1 x 2 = 2
.
.
.
1 x 10 = 10
---------------------------
2 x 1 = 2
2 x 2 = 4
.
.
.
1 x 10 = 10
---------------------------
.
.
.
10 x 9 = 90
10 x 10 = 100

Answer 1

For future reference, you can include code in 3 ` (top left of the keyboard, not the single-quote) to get it to highlight like
```
og
```
``(`)
code
``(`)

---------------------------------
your code:
```
for (int i=1;i<=10;i++){ //line 1
for (int k=1;k<=10;k++);{ //line 2
System.out.println(i+"x"+j=+(i*j)) //line 3
}
}
```
Line 1 looks pretty good.
Line 2 has an unexpected semi-colon after the ). A ; symbolizes the end of a statement, and a for loop is a code block, it uses {}, and doesn't end in a ;. You'll get used to it pretty quickly.

Line 3 has a couple issues - first, it needs to end in a ;, because it is a statement. Also, in System.out.println(); - you essentially put in a series of variables, and strings ("I am a string"), attached by the + symbol. However, you have a random = sign in there - cleaned up it should look like:
```
System.out.println(i+"x"+j+"="+(i*j)); //line 3
```

Answer 2

Oh and you use variables i and k in the for loops.. so substitute 'j' for 'k'

Answer 3

There is no semi colon at the end of println statement.
