for (int j=1;j<=i;j++){
System.out.print((i*j)+"\t");
}
System.out.print("\n");
}
}

}

Answer 2

public static void main(String[] args){
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(i*j+" ");
}
System.out.print("\n");
}
}

Answer 3

for(int i=1;i<=9;i++){
int j=1;
String result="";
while(j<=i){
result += i*j + " ";
j++;
}
System.out.println(result);
}
