Question: I am trying to solve a problem using java where I have to print the number the same number of time as the number itself. For example 1 will be printed once 2 twice 3 thrice and so on. I tried to attempt the question using nested loop but it is going into infinite loop. Please pinpoint the mistake in the code.
Thanks!

```
 {                                         
    for (int i=1;i<=10;i=i+1) {
        for (int j=1;j<=i; j=i) {
            jTextArea1.append(""+j);
        }
    }
 }          

```

P.S I attempted this question using netbeans.

Answer: 
**The problem is in the second loop.**

Making progress as **j=i** and checking for **j<=i** will always give the **true** result. So there is the infinite loop.

You may want to change the progress to something like `j= j+1`

**Edit:** You need to do this

```
for (int i=1;i<=10;i=i+1) {
    for (int j=1;j<=i; j++) {
         jTextArea1.append(""+i);
    }
}

```
The problem caused in second loop during initialize `j = i`. This interrupt the var `j` to be increment. It should be `j++` or `j += 1` or `j = j + 1`. Example here...

```
for (int i = 1; i <= 10; i++) {
    for (int j = 1; j <= i ; j++) {
       jTextArea1.append(" "+i);
    }
}

```
