Identify the error in the programs and write a corrected code:

1. public class Test{

public static method1(int n , m){

n += m;

method2(3.4);

} // end of method 1

public static method2(int n){

if(n > 0){

return 1;

}

else if(n == 0){

return 0;

}

else if(n < 0){

return -1;

}

} // end of method 2

} // end of class

2.

public class TestPrint{

public static void main (String[] args){

nPrintln(5, "welcome to Java!");

} // end of main

public static nPrintln (String msg, int n){

for(int i=0; i

System.out.println(msg);

}

} // end of nPrintln

} // end of class
